Hey, I was tryna figure out how to post a pic too. I think u have to be a bluelighter first. It wanted me to add a link or address or something instead of using an attachment. Hope u get an answer soon cuz I would love to know as well.
takes 50 posts to become bluelighter. You should have the 'go advanced' button under the reply box. In the advanced screen there is a link to post photos. Actually there is one in the quick reply box as well-2 links down from the spell check button.
