I have Fotki, store literally thousands of pic on a paid for account.
I do NOT recommend them. They have, and continue to lose my photos. It seems that every album I have (there must be over 100) has missing photos. Just a red X where the photo used to be. When I was new to the site, I would write to their service dept and ask where my pic was. It was confusing as they wanted a link to either the photo, or the page, but not both. Even then, they said there was nothing they could do. Now I have too many photos to transfer. I would like to hear from anyone else if they are missing any photos from Fotki.
