ok, there's a button that's for pictures. this button:
paste in your picture's URL. you need to get the image hosted elsewhere, like on imageshack.us or photobucket. copy and paste the direct link to the image into the little window that pops up when you hit the picture button.
then it should show up.
you can also use the Attachment thing. hit browse, get a picture off of your computer, and upload it.
