Imágenes

De WikiDoc

Antes de Insertar una Imagen en un Capítulo, Primero Debe Subir la Imagen en el Servidor de WikiDoc

Las imágenes pueden ser insertadas en una página de WikiDoc solo si ya han sido subidas al servidor de WikiDoc (la computadora que sirve todas las páginas que usted puede ver). Si las imágenes que quiere insertar no estan en el servidor, las puede añadir al servidor (un proceso tambien conocido como "subiendo" las imágenes, o "uploading"). Cada página de WikiDoc tiene un enlace en su margen izquierdo, llamado Subir archivo, que tiene todas las informaciones y detalles para añadir o subir la imágen al servidor.

En la página de Subir archivo, verá los dos cuadros siguientes:

Donde dice "Nombre del archivo origen:" pulse el botón gris que dice "browse" y encuentre el archivo que quiere añadir a WikiDoc en el disco duro de su computadora.

En la parte que dice "Nombre del archivo de destino:" simplemente escriba el título que le quiera dar a la imágen en WikiDoc. Por favor escoja un título que describa la imágen apropiadamente para que se pueda encontrar y ser catalogada por otros motores de búsqueda.

Después, pulse el botón que dice "Subir archivo".

Luego, la imágen aparecerá. Una pista: copie el nombre del archivo para que pueda insertarlo en la página de interés de WikiDoc.

Cuando usted u otra persona añade una imágen al servidor, esa imágen entonces puede ser insertada en cualquier número de páginas.

Puede encontrar los nombres de archivos de las imágenes que se han subido a WikiDoc en la Lista de imágenes. Necesitará saber el nombre de archivo de la imágen para insertarla.

Puede ver las imágenes que se han subido a WikiDoc en la Galería de imágenes nuevas

Instrucciones Básicas para Insertar Imágenes en una Página de WikiDoc

Solamente las imágenes que han sido subidas a WikiDoc pueden ser usadas. Para subir imágenes, use la página de subir archivos.

Inserte el Código de la Imágen

Images are placed on a page by typing a line of image code along with the other text. As with the typing of text, this is done in the editing window of the page being edited. Selecting the edit this page tab at the top of the page accesses the editing panel. Sign-on first so that your work will be credited to you in the record keeping.

Before placing the code, first consider the best place for the image. This usually means thinking about how the text will look when it wraps. For example, sometimes the work looks best when the image is level with the start of a section. If you want it to start there, then make an empty line immediately under the heading or immediately above it, depending on which you think looks best, and type the image code, (given later). The extra line will be ignored apart from the production of an image.

Press the Show preview button at the bottom of the editing window and wait for the system to display the reformatted page. If the image was placed on the left or the right then the text will be seen to wrap around the image from the very top of the section. If the center was selected, (or none), then the text cannot wrap, and the text will move to a point below the image. If the result is not as expected, then the text can be changed as often as necessary, until it is right. When the work is right, then press the Save page button at the bottom of the page.

Most images on the Wiki server are simply too big to display in their full sizes. In nearly every case an image reduction will be needed. The server also expects to know where to place the image, as well as what kind of frame is required. Does it need a caption? With these common requirements in mind, and to save the user much valuable time, it is proposed to go straight onto the recommended format; the one having all of the basic options in it. A selection of common examples using the recommended syntax is given in the "Examples" section below.

Examples

A picture: 
[[Image:humanbody.jpg]]

With alternative text:
[[Image:humanbody.jpg|Anatomy]]

Floating to the right side of the page
and with a caption:
[[Image:humanbody.jpg|frame|Anatomy]]

Floating to the right side of the page
''without'' a caption:
[[Image:humanbody.jpg|right|Anatomy]]

Linking directly to the description page
of an image:
[[:Image:humanbody.jpg]]

Linking directly to an image
without displaying it:
[[media:humanbody.jpg|Anatomy]]

Example:
<div style="display:inline;
width:220px; float:right;">
Place images here </div>

Example: {| align=right
|-
| 
Place images here
|}

More Detailed Instructions for Inserting Images and its Syntax

Type

• "thumbnail" or "thumb": Image is scaled down to a standard, user specified width, by default 180 pixels, and a box is added around the image. If a caption is written, it is shown below the image. Image defaults to placement on the 'right' unless overridden with the 'Location' attribute (see above).
• "frame": Original image size is preserved, and a box is added around the image. If a caption is written, it is shown below the image.
• (nothing specified): Original image size is preserved, no border is added around the image. If a caption is written, it is not shown.
• "border": Same as if nothing is specified, but a border is added around the image.

Location

• "right": Image including its box is placed on the right side of the page. The article text that follows the image flows around the image.
• "left": Image including its box is placed on the left side of the page. The article text that follows the image flows around the image.
• "center": Image including its box is placed in the center of the page. The article text that follows the image is placed below the image.
• "none": Image including its box is placed on the left side of the page. The article text that follows the image is placed below the image.

Size

• "100px": Scales the image down to make it 100 pixels wide. Replace any number for 100. If you specify "thumbnail" and a value here, this value will take precedent. If the image is already smaller than your specified value, the image stays at its size.
• "100x200px": Scales the image to be no wider than 100 pixels and no higher than 200 pixels. Image will keep its original aspect ratio

Caption

Any element which cannot be identified as one of the above is assumed to be caption text.

New advanced syntax for inserting images

In the syntax [[Image:filename|options]] (e.g. [[Image:Humanbody.jpg|thumb|100px|left|Anatomy]] shown in the left), several options can be set when including an image. Those affect the placing of the image, its size or the way the image will be presented. The options are right, left, center, none, sizepx, thumbnail (thumb), frame, and alternate (caption) text.

The options can be combined, and vertical bars ("|") are used to separate options from each other. The options can be put in any order. An unknown option is taken as the caption text, but this seems to appear only if thumbnail is specified. If there are two or more unknown options, the last one upstages the rest: [[Image:Humanbody.jpg|thumb|Anatomy|200px|right|Human Body]] (shown on the right).

Here is the description of the options other than the caption text:

right 

Imagen:Humanbody.jpg

The image is right-aligned, and text floats to the left of the image: [[Image:Humanbody.jpg|right|70px|]] (shown on the right).

left 

Imagen:Humanbody.jpg

The image is left aligned, and text floats to the right of the image: [[Image:Humanbody.jpg|left|70px|]] (shown on the left).

center 

The image is centered, and...

Imagen:Humanbody.jpg

the text following the image starts below it: [[Image:Humanbody.jpg|center|70px|]] (shown above).

none 

The image is put at the left, and...

Imagen:Humanbody.jpg

the text following does not float to the right (or to the left, obviously), and starts below it: [[Image:Humanbody.jpg|none|70px|]] (shown above).

Notes:

Imagen:Humanbody.jpg

The above four options are incompatible. When used combined, the last one overrides the rest: [[Image:Humanbody.jpg|none|right|center|left|70px|]] (shown on the left).

Imagen:Humanbody.jpg

What is between the last vertical bar and the closing brackets ("]]"), void or not, is taken as the last option, and works as usual. For instance, when the last option is right, the image is right-aligned, and text floats to the left: [[Image:Humanbody.jpg|70px|right]] (shown on the right).

Imagen:Humanbody.jpg

Imagen:Humanbody.jpg

70px

In particular, if the last option is the void text (that is, if there is nothing between the last vertical bar and the closing brackets), the caption is not displayed: [[Image:Humanbody.jpg|thumb|This text is not displayed.|70px|left|]] (shown on the left) and [[Image:Humanbody.jpg|thumb|This text is displayed.|70px|right]] (shown on the right).

sizepx 

Imagen:Humanbody.jpg

This option renders a version of the image that's [size] pixels wide (e.g. [[Image:Humanbody.jpg|right|50px|]] shown on the right). Height is computed to keep (i.e. the shape of the image)

Notes:

Specifying a size does not just change the apparent image size using HTML; it actually generates a resized version of the image on the fly and links to it appropriately. This happens whether or not you use size in conjunction with thumb.

This means the server does all the work of changing the image size, not the web browser of the user. By having the server do all the work means faster downloading of pages. It also means that larger images can be stored on the server without any slowdown by the browser (especially on dial up telephone lines.) Only the data for the actual size on the page is transmitted.

From MediaWiki 1.5 the default thumbnail width can be set in the preferences, so it is recommended not to specify "px", in order to respect the users' preferences (unless, for a special reason, a specific size is required regardless of preferences, or a size is specified outside the range of widths 120–300px that can be set in the preferences).

If you specify a "frame" option the image will not be scaled, and no size specifiers will be in the HTML. The image will be rendered at full size

Imagen:Humanbody.jpg

When there are two or more "size" options, only the last one is valid: [[Image:Humanbody.jpg|right|50px|80px]] (shown on the right).

thumbnail, thumb 

Imagen:Humanbody.jpg

Imagen:Humanbody.jpg

Anatomy

The thumbnail (thumb) option generates a image. It is automatically resized when the "size" attribute is not specified. Without the options left, center, and none, the image is normally on the right. If the image has a caption text, it is displayed in the lower margin. E.g. [[Image:Humanbody.jpg|thumbnail|left|100px|]] (shown on the left) and [[Image:Humanbody.jpg|thumb|Anatomy]] (shown on the right). Note: thumbnail (thumb) cannot be used in lists.

frame 

Imagen:Humanbody.jpg

Anatomy

With this option, the embedded image is shown with its actual size enclosed by a frame, regardless of the "thumb" or "size" attribute, and the caption, if any, is visible in the frame. Without the options left, center, and none, the image is normally on the right: [[Image:Humanbody.jpg|frame|thumbnail|50px|Anatomy]].

With none of the options other than sizepx and alternate (caption) text, an embedded image is rendered inline.

text text text text text text
[[Image:Humanbody.jpg|150px|Anatomy]]
text text text text text
[[Image:tst.jpg|100px|This is a puzzle.]]
text text text text

gives

text text text text text text Imagen:Humanbody.jpg text text text text text Imagen:Tst.jpg text text text text

The option none can be used to have thumbnails without left- or right-alignment. This is probably most useful for tables. This is an example:

Thumbnail with caption text underneath that has one or more links

It is also possible to include links in the caption text, e.g.:

[[Image:Humanbody.jpg|right|thumbnail|This is the [[Palace of Westminster]] in London]]

Just make sure the number of opening and closing square brackets are right. One extra or missing would mean the entire image syntax line would not work.

Additional caption formatting options

Additional caption formatting options are possible.

[[Image:Humanbody.jpg|right|thumbnail|<div align="center">This is <span style="color: green">the </span><br /> [[Palace of Westminster]]<br /> '''in <span style="color: red">London</span>'''</div>]]

All of the normal text formatting options work.

How Do I Insert a Whole Bunch of Pictures in Gallery like format?

If you use the following text below, the image below this will appear:

<gallery>
Image:humanbody.jpg 

Image:Femoral artery and branches.jpg

Image:Femoral-triangle.jpg

Image:Femoral-traingle-2.jpg

Image:Femoral-artery1.jpg
</gallery>

This code generates the following image:

How Do I Keep All The Text From Floating Around The Image? How Can I Get The Text To Begin Again Below the Image? Cancelling The Floating-Around-Image Mode

After having had an image floating next to text, putting further text below it and again using the full width can be done with the following markup. This blocks an image from appearing next to the material following this markup, possibly due to aesthetic reasons or a change in topics.

<br style="clear:both" />

For legacy align="right" (etc.) floating this isn't good enough; legacy browsers would ignore inline CSS. To cancel floating under all conditions the following markup (valid XHTML 1.0 transitional) works:

<br clear="all" />

The same code can be issued by using template {{Clr}} or {{-}} in certain namespaces (En, meta).

How Do I Align the Gallery to the right or left and have text float around it?

To achieve the format below:

Compared to normal arterioles on the left, the arterioles from a patient with hyertension (middle) show moderate periarteriolar thickening and fibrosis. Shown on the right is a patient with HCM in which there is even more signficant periarteriolar thickening and fibrosis. This thickening of the wall of the intramyocardial arterioles leads to an increased wall/lumen ratio, subendocardial ischemia and impaired coronary flow reserve.

Use this code:

<gallery
align="right"
>
Image:Arteriole-normal.jpg|Normal arteriole
Image:Arteriole-hypertensive.jpg|Hypertensive arteriole with wall thickening and myocyte hypertrophy
Image:Arteriole-hcm.jpg|Arteriole in HCM patient with periarteriole fibrosis and thicknening
</gallery>

This thickening of the wall of the intramyocardial arterioles leads to an increased wall/lumen ratio, subendocardial ischemia and impaired coronary flow reserve.

Linking To A Page That Has A Detailed Description Of The Image

If you want to make a link to the description page for an image, use a leading colon before "image:" in an intra-wiki link, like this: [[:image:humanbody.jpg|humanbody]] which yields: humanbody
