Push "Go Advanced" below this post.
If the image is on your computer, push the "Manage Attachments" button below the text box, then "browse", select your image, push "upload", wait for it to upload, close the window, submit your post. Max. size is 100KB, which is small

If the image is hosted somewhere on the net, push the image button thingy.

Attached a pic showing the buttons, 'cos I'm bored.

Now I'm confused... Ihad to get the pic compressed to this crappy size (ok, I overdid it a bit) to fit into 100K, so how do others attach nice clear pics?
Anyway, have the image hosted elswhere, imageshack.com or whatever.
