Dont think so but there is a photobucket app which makes things easy enough, you do need to sign up for it though if you dont already use it. It is free though.
if you browse the forum on ipad or iphone, i can upload pics direct from my "i" device, just click on the picture of the tree you see and it will ask if you want to take a pic, or choose from your library. simples!
Apologies, you can indeed do it that way, I have always used photobucket and never used the upload from pc option as PB gives you the img tagged links already.
