I'm trying to upload pictures as well but I think my account was disabled?
Until you're validated, your account's abilities are very limited. You can basically post here and on the Public Forum, and if I'm not mistaken you can't upload pictures. If you want to show us pictures I believe you need to upload them to a third party site and post the link.
Yes I did validate my account but it says the administrator has to approve it but they have not yet.
