Yep. I was doing http://www.ubuntulinux.com/wiki/imagename.png but same
difference ;)

Yeah actually the HelpOnEditing needs a bit of work. It was basically
copied over from the moinmoin website so it has some discrepancies.

The "anchor" macro is necessary for this. I was talking to Simon
yesterday and he said that perhaps there may be a possibility of adding
macro capability to the wiki. They would be useful for this task, and
also there is one for adding html options (alt, align, size etc) to
inline images. Although this doesn't matter too much for icons, it would
be incredibly useful for larger images like screenshots.
