If you're a user of the Web Browser Firefox I'd like to make a recommendation on an Extension you can install to make your Thumbnail browsing easier.
Here is a preview of what the addon does:
Whenever you mouseover a thumbnail it will pop up the image in its original size instead of linking you to another page to view the full size image.
Below, you will find a zip file which contains an XPI file. Extract it to your desktop and then open Firefox. Go to File > Open File > Select ThumbnailExpander.xpi and install it. Once it is installed, restart Firefox and you should be good to go!
