As far as viewing graphics goes, Lightbox development has gone a long way for making it look more professional and pretty. What if you could add that to a Web site that didn’t provide it in the first place? To do that, you will need the Greased Lightbox Greasemonkey user script.
Greased Lightbox is a Greasemonkey/Creammonkey/Opera user script designed to enhance browsing on websites that link to images such as Google Image Search, Flickr, Wikipedia, Facebook, MySpace, and deviantART.
This script adds a nice interface to any graphics you might be browsing. I have been using a lightbox script for WordPress on SB1Online.com for some time now and I just love it. Adding that functionality to a Web site that doesn’t have it is even cooler.
To use this script you must have Greasemonkey for Firefox installed.
