I can't seem to use the Image options under 1.3.9 (or 1.4.0 for that matter) as described here:

http://en.wikipedia.org/wiki/Wikipedia:Picture_tutorial

Are these capabilities limited to wikipedia or are they part of the base mediawiki also?

For example, I have tried without success to do this: [[Image:foo.jpg|right|50px|frame|Some Caption]].

Thanks for the help,

George
