I haven't paid for Pro yet (paying for Picasa's Pro service already), and I used up my bandwidth last month, so I just now updated with some very non-GI Joe pics. Images from E3, the annual video game expo!
Flickr has fantastic community tools, but it doesn't display the images as large as Picasa does (unless you start clicking to larger versions). The Picasa images just fit the window, whatever size it is. If only Google could catch up on the community side!
