OK, I'm not feeling more insane than usual but I can't for the life of me get the "Embedded Image" tag in the wiki to actually pull in and embed an externally linked image.

WTB: a clue, PST.

[edit] Example: I want to embed this image into a wiki page: http://www.l00py.net/images/under-construction.gif

When I use this tag: [[Image:http://www.l00py.net/images/under-construction.gif Test Image]]

I get a text link showing "Image:Http://www.l00py.net/images/under-construction.gif Test Image" and no actual image.
