PicLens is an immersive full-screen experience for viewing photos on the Web. Supports the presentation of images in the following web sites:

Flickr
Facebook
Google Images
Yahoo Images
Friendster
Picasa Web Albums
Media RSS

This is a pretty slick little tool for Firefox and Safari. Basically if you are visiting one of the sites listed above, you just need to mouse over an image and click the arron icon to engage the tool. It darkens the screen and the image grows full size to fill the screen. Am thinking this would be great for presentations and classroom demonstrations and such. Throw some images into Flickr, arrange, and you have an instant, low overhead, presentation.
