David's Picasa Web Albums
Google has updated Picasa for the first time in over a year with the beta (or test) release of Picasa Web Albums. With it they give you 250MB of free space, or for $25 a year they give you a full 6GB of space to use for over 25,000 photos online.
Right now it is invitation only. I received one today and uploaded a few albums to it including Jane's 75th birthday party, a few shots from Bermuda and some Pelican shots.
