I have had good luck with Photobucket. Easy to use. Not sure how much you can load, but I am not sure any of the photo sites are meant to be a backup for your PC. I have thousands of digital pics from various additions to the house and other projects (my lifted trucks), but only a hundred or so on Photobucket. Usually just the ones for posting on forums. For a backup, I burn DVDs and put in the safe deposit box.
I am sure I'll have several thousand more this time next year when the Cobra is close to complete.....
