Don't preview it — just send it.
Previewing a pic seems to upset the system.
There was this pro photographer who was getting rid of his old wood tripod. He advertized it for only $25.00 so i didn't expect much. Turns out it is a beautiful ultra sturdy Camera Equipment Co. Professional tripod made in the 1950's for movie cameras. Here is the only photo of it I could find..
Well, the pic showed up in preview but not when I posted it. What am I doing wrong?
