sounds like the dreaded "timing out before submitting" deal is thwarting your efforts. Might have to have Ed/Slab check you out. We did have some members with the same type of problems ... computer would time them out before they could get all of their message typed in and submitted. I don't know what the fix ended up being ... as I've not had that problem, myself.
I'll refer this thread to Ed, so sit tight and watch for a reply from him ... or a PM from him. We'll get your picture posting problem solved ASAP.
