Here is an exciting add-on for browser Google Chrome to turn your favorite image sites such as Google image search, Yahoo search, Picasa, Flickr and Facebook into a slideshow.

What makes it interesting is that you can preview images as a slideshow in your browser.

While testing I found it that it works fine with most image sites. When you enter such a photo site an icon will appear on your browser. Click on it will let you on/off the feature.
