PictureTuner

From MetaConvergence:

PictureTuner lets you publish & share photos directly from your computer, in 3 simple steps. No more tedious uploading to a web site that may close down or start charging monthly fees. You retain full control since the pictures remain safely in your computer. You can take shared albums online/offline with a single click - no need to upload to/delete from a remote web server.

You can preview pictures published by other users in an innovative & versatile desktop window, view the full-size image as a slide show, or use it as a screen saver. No more clicking endlessly on thumbnails & waiting for images to load. The pictures are served 'live' from the publisher's computer directly to yours.

While viewing, easily snap and save the pictures you like, or set them as your desktop wallpaper. There's even a build-in MP3 player so you can listen to your favorite tunes while enjoying the photos.
