What is the size limit for uploads? I got denied on a 290 KB picture, says it is too big.
You have to use another imaging source. Try Photobucket or something similar.
The forum has a limit of storage, if I understand correctly.
There is a topic with more discussion here (http://gstwins.com/gsboard/index.php?topic=69620.0)
As Big Rich stated, the best alternative is to use an image hosting site and then img tag from that, such as Imgur or Photobucket.
