PicLens provides an immersive full-screen experience for viewing photos on the Web. It can be used on Flickr, Facebook, and image search results from Google and Yahoo, and any page that supports Media RSS.

To use the software, move your mouse over an image and click the PicLens button that fades in. With one click, the image expands into full screen mode, where you can browse through the photos on the page in high resolution. You can jump between photos or start an automatic slideshow by using the buttons at the lower-left. You can also press the space bar to play and pause the slideshow, and the arrow keys to move between photos. Pressing any other key will take you back to your browser.

You can click on a thumbnail in full screen mode to jump directly to that image. If there are more images than fit on the thumbnail strip, you can use the arrows to the left and right of the strip to scroll.
