Cooliris is a web browser plug-in that allows users to visually search images and videos across multiple websites like Google Images, YouTube, Flickr and others. It presents search results in an attractive slideshow format. The company makes money by including advertisements within the slideshow results. While not likely to become a mega company, Cooliris has appeal due to its ability to search across many sites and create online slideshows, skills that will grow more useful as user-generated content increases.
