I don't know anything about nothing but have you tried opening a free photobucket account and uploading the picture to there, than posting the i age code to thread.......
I hope I'm not leading you on a wild goose chase.....
An img link from photobucket pasted into the message is how I do it. It can all be done from your phone/tablet. Let me know if you need specific instructions.
Fuck this place. Second rate hack playing in a yard that's too big for him.
