Image 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.
 * 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.

Image Formatting
The following table shows the effect of all available formats.

When the height of an image in thumbnail is bigger than its width and you find it too outstanding, you may try the option, which will try to adjust its size to more desirable size.

Note that by writing, you can use a different image for the thumbnail.

Image Alignment
Note that when using  or , the default alignment will be.

Size and Frame
Among different formats, the effect of the size parameter may be different, as shown below.


 * When the format is not specified, or only ed, the size can be both reduced and enlarged.
 * An image with  always ignores the size specification.
 * The size of an image with  and   can be reduced, but can not be enlarged beyond the original size of the image.

For how it appears when its size is not specified, see Format section above.

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:

Parameters
The gallery tag itself takes several additional parameters:
 * : sets a caption on the gallery.
 * : sets the widths of the images.
 * : sets the (max) heights of the images.
 * : sets the number of images per row.
