Wikipedia:Extended image syntax
Old syntax
The old syntax for images is [[Image:Westminstpalace.jpg|alternate text]] whis is rendered inline and the alternate text is used as alt=-attribute for use as mouse popup and for screen reader.
Example
New syntax
The new syntax is backward compatible, so articles don't have to be changed. Parameters indicating how to render the image can be given, using the syntax [[Image:Westminstpalace.jpg|options|alternate text]]. Available options are:
- thumbnail, thumb
- generates a thumbnail image floating to the right, using the alternate text for both alt=-attribute and as a caption. An "enlarge"-icon is added. Example: [[Image:Westminstpalace.jpg|thumbnail|The Westminster Palace]]
- right
- make the image right-aligned, can be used with and without specifying thumb
- left
- same as above, but left aligned.
- none
- The image will be rendered inline, even if the thumbnail-option is set
- sizepx
- render a thumbnail version of the image that's [size] pixels wide (e.g. '150px'). Height is computed to keep aspect ratio.
Vertical bars are used to separate options from each other and from the alternate text. The last option is used as alternate text. Unknown options are skipped.
The options can be combined, e.g. as [[Image:Westminstpalace.jpg|left|80px|Westminster palace]] or [[Image:Westminstpalace.jpg|thumb|80px|The Palace]].
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:
| How to use none | |
|---|---|
| London's palaces | |
| Westminster Palace | |
| Buckingham Palace |  |
