So: I need to find a site to act as a media locker for all these photos I gotta scan in. I kinda like Picasa, but I know there's tons of choices out there. Just want to go with the one most likely to suit my needs. Basically, since these will be photo scans, I want to use a site that gives me big capacity and allows me to keep permanent access to the original, full-sized uploads. Want it to be reasonably priced and allow for a good level of control, tagging, etc. Also want to make sure they're a site that's going to be around for years to come (re-doing this exercise is not something I want to have to do, since I can tell it's going to me a months-long project to scan all these photos in and upload them).
