We found a way around the issue of sites not allowing off site image linking. Tis naughty, but meh, who cares, it works and they are none the wiser. It hardly effects their bandwidth, if at all.
Anyway if you can see the image below here's how it's done:
You need to add the following line BEFORE your picture link:http://invis.free.anonymizer.com/
so the give an example it would look like this, note without the spaces after and before [img] tags
Then here you'd put the usual image URL and end it with [/img]
LOL I hope I did that right :P
