Cooliris, formerly known as PicLens, is a web browser plugin made by Cooliris that provides interactive full-screen slideshows of online images.
The software places a small icon in the corner of an image thumbnail when the mouse moves over it, which launches into a full-screen photo viewer when clicked, but without giving an option to save any of the pictures shown. More recently, Cooliris also allows viewing of local picture files.
The Cooliris plugin is available for Safari, Firefox, Google Chrome, and Internet Explorer, and for Windows, Mac OS X, Linux, and iPhone.
The software is compatible with and any web site that implements Media RSS <link> tags in their HTML pages, including: Google Image Search, Yahoo! Image Search, Ask.com Images, Live Search Images, AOL Image Search, Flickr, Photobucket, Picasa, Fotki, FotoTime, deviantART, SmugMug, Facebook, MySpace, Bebo, hi5, Friendster, YouTube (for videos)
