I store my photos on smugmug. It does have an annual fee, but it stores and lets me access the full resolution images which most other sites do not. I have a ton of photos and there is no size limit on how many or how often you upload.
sorry, I didn't see this! I use iPhoto library manager. http://www.fatcatsoftware.com/iplm/
