If you're still struggling, the below thread has some advice on how to post pictures. The main thing I struggled with at the beginning was picture size. Avatars must be no bigger than 75x75 pixels. And photos attached to posts have a restriction, too. I usually post 400 x 600 pixel pictures for attachments.
