Liam Burke sends word of iMobio.

iMobio is a hosting site for your images, videos and recordings. So if you run out of space on your mobile just send your images via MMS to the email address and keep a permanent copy. Sending an image allows others to comment on and rate your images. There is also a tagging section to quickly find your images.

iMobio. Robin Blanford also recently wrote up a good tutorial on how to do this sort of thing with flickr.
