CoolFlick: It's like Cooliris without the plugin
CoolFlick is a web page that provides some of the functionality of Cooliris. But there's nothing to install. Just visit CoolFlick, type in a search term, and browse through the photos of cats, computers, or landscapes, or celebrities to your hearts content. You can click anywhere on the screen and drag the wall of pictures, or you can click on an image to make it larger. If you want to visit the original page, just click the box and arrow icon that shows up when you select an image.
If you want to browse videos, Google Images, Amazon listings, or other sites, you'll still be better of with Cooliris. But if you just need a quick fix of some pretty pictures in a pretty interface, CoolFlick might do the trick.
