Bear on a Bicycle has posted a thread on this can't seem to find it either.
Basically, get yourself a photo storage account at Flickr or PhotoBucket or some other reputable place. Follow their instructions for uploading your photographs.
Then find the link to the photo, again the photo site will show you the link - there maybe several versison of the link, grab the http:// version without any html markup.
Then back here at the forum, create a new message and you click on the yellow square icon with a picture of a grey mountain and a grey sun. A message box will ask you for that link. Paste it into that box. Then click Ok.
Your photo will then appear in your message.
