! Introduction
|
|
|
|
The image widget displays images that can be specified as a remote URL or the title of a local tiddler containing the image.
|
|
|
|
! Content and Attributes
|
|
|
|
Any content of the `<$image>` widget is ignored.
|
|
|
|
|!Attribute |!Description |
|
|
|source |The URL of the image, or the title of an image tiddler |
|
|
|width |The width of the image |
|
|
|height |The height of the image |
|
|
|tooltip |The tooltip to be displayed over the image |
|
|
|alt |The alternative text to be associated with the image |
|
|
|class |CSS classes to be assigned to the `<img>` element |
|
|
|
|
The width and the height can be specified as pixel values (eg "23" or "23px") or percentages (eg "23%"). They are both optional; if not provided the browser will use CSS rules to size the image.

! External Images and the ''_canonical_uri'' field
|
|
|
|
When used to display tiddler-based images, the image widget operates in two distinct modes:
|
|
|
|
* If the ''_canonical_uri'' field is present then it is used as the ''src'' attribute of the generated `<img>` element and the ''text'' field is ignored
|
|
* Without the ''_canonical_uri'' field, the image widget generates an `<img>` element that embeds the image data directly using a `data:` URI.

See ExternalImages for more details.
