Help:Images

This page explains the image syntax when editing STO Wiki. You or another user must upload an image before you can use it on a page.

Syntax
The full syntax for displaying an image is:



Where options can be zero or more of the following, separated by pipes:
 * border, frame, thumb, or frameless: Controls how the image is formatted
 * left, right, center, none: Controls the alignment of the image within a text
 * baseline, sub, super, top, text-top, middle, bottom, text-bottom: Controls the vertical alignment of the image within a text
 * {width} px: Resizes the image to the given width in pixels
 * {width}x{height}px: Resizes the image to fit within the given width and height in pixels; it is possible to specify only the height by writing x{height}px
 * Note that the image will always retain its aspect ratio.
 * link={destination}: Allows to link to an arbitrary title, URL or just nowhere
 * link= : Will display an image without link, e.g.  → Example.jpg.
 * Note that link cannot be used in conjunction with thumb as thumb is always meant to link to the larger version of the image. In addition, link cannot be used with frame.
 * alt={alternative text}: For changing the alternative text (alt="") of an image
 * Special cases:
 * page=1: Displays the specified page when showing a djvu or pdf file

The options can be given in any order. If the given options conflict each other, the latter is applied, except for the format options, where the options take the priority in the order of frame, thumb, and frameless and/or border.

If a given option does not match any of the other possibilities, it is assumed to be the caption text. Caption text can contain wiki links or other formatting. If no caption text is supplied a caption is automatically created showing the file name; to completely remove the caption, set it to. For example,  →.

Stopping text flow
On occasion it is desirable to stop text from flowing around an image. Depending on the web browser's screen resolution and such, text flow on the right side of an image may cause a section header (for instance, == My Header == ) to appear to the right of the image, instead of below it, as a user may expect. The text flow can be stopped by placing    before the text that should start after the image.

Gallery of images
It's easy to make a gallery of thumbnails only, not other images, with the  tag. The syntax is explained on the Help:Gallery page.

Link to description page
If you put a colon before , the image will not be embedded and the link will lead to the description page of the file, like so:

Sunflowers

Link to another page
This will make a 50px width picture with a link to the page MediaWiki:





Link directly to file
You can use the pseudo-namespace “   ” to link directly to a file, bypassing the description page, like so:



You can also use:

/

...which can be used to link to a potential file, even if it doesn't exist.

Requisites
Before using images in your page, the system administrator of your wiki must have and a user has to upload the file. System administrators may also set the wiki to accept files from, such as the Wikimedia Commons. For server side image resizing it is necessary to have a scaler configured (such as GD2, ImageMagick, etc.).

Files at other websites
You can link to an external file available online using the same syntax used for linking to an external web page.



Or with different text:
