If the image source is the title of an image tiddler then that tiddler is directly displayed. Otherwise it is interpreted as a URL and an HTML `<img>` tag is generated with the `src` attribute containing the URL.
A tooltip can also be specified:
```
[img[An explanatory tooltip|Motovun Jack.jpg]]
```
Attributes can be provided to specify CSS classes and the image width and height:
The image syntax is a shorthand for invoking the ImageWidget.

You can also display an image stored in a tiddler by transcluding that tiddler. The disadvantage of this approach is that there is no direct way to control the size of the image.
