take your pics to
www.picresize.com and resize to 1000 pixels by 1000 pixels and then save them. After you Write whatever it is you wanted you write in your thread, scroll down to "additional options" and select "manage attachments. Thsi will ask you to browse and locate the resized pic and the click "upload". That should be it. If it doesn't work, go and resize smaller. I'm not too computer lierate so I cannot explain why ths happens. If it does, drop the pixels to 400X400 - always works for me. -good luck
