Well i would post my pic but don't know how. I clicked the two picture tab, second row 5th form the left and it uploaded it somewhere not sure where!
If you succesfully uploaded the pic, what you do is go to your profile, select the "View items" button from the drop-down list. Click your desired pic, then select "Details". Under the pic, find the BBC code (Looks a bit like this [ smg id=2462] )
Simply copy that code, brackets and all, then paste into your reply.
