[Web4lib] Advice on cloud photosharing sites?

[Jennifer Heise]

Greetings!
Because we're a little crunched for space right now, I'm considering
recommending that the library use an external cloud/web photosharing site to
store our event photos. (Right now they are living on the Dean's external
hard drive, so they are difficult to get at, and not backed up.) I've looked
at Flickr, and I personally use Picasa, but what photosharing sites are
other libraries using?
Thanks!
