This is Mark using another browser / test account. This test account has the same permissions as yours, so I can see. I just uploaded the Panda image I used before for Jax's avatar, no problem. When you click "attach files" "manage attachments" you have the opportuntiy to attach a pic from your PC (using browse). When you do this, you can then remove that image if you want, as you have a limit of 1 image at this time.
Regards
Mark
