Cooliris, formerly known as PicLens, is a web browser plugin that provides interactive full-screen slideshows of online images. The plugin is available for Safari, Firefox, and Internet Explorer. At present, the software is compatible with 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), Gallery, and any web site that implements mediaRSS <link> tags in their HTML pages. 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.
