One of the most commonly used feature of Social networking sites is photo sharing with your friends. Mostly these photos will be displayed as thumbnail although you can maximize one by one. Thumbnail Zoom is a Firefox add-on which allows you to zoom thumbnail images from social networking sites without having to open the images. It works on major social sites including Facebook, Twitter, MySpace, Amazon, Picasa, Flickr, LinkedIn and Hi5!.
Once installed, all you need is to hover on the thumbnails and you can see the image in full size with a frame. The add-on works neatly and shows the images pretty quickly. From the settings panel, you can actual set a time delay for displaying the images and also set which all networks the add-on should work.
Thumbnail Zoon should be helpful for you if you have lots of photos to view in social sites.
