I find that if you don't allow each pic to load before selecting the next one they won't work. Also you can't select full image all and then hit post right away, you have to wait until the pictures show up in the post(the one your making) before hitting post reply.
It takes a lot more time and doesn't always work right.
That sounds like a load of crap if
@Darin said that.
Opeforum is alive and well and they're still running the setup that AS used to have. Maybe they should update to that, oh wait...
