I have used this image magnifier script on a number of websites. It is a superb piece of coding - lightweight yet worked on all platforma and browsers I tested it on (PC and Mac, IE, Firefox, Opera, Safari). It is XHTML compliant. It is easy to install - you don't need much technical knowledge at all. I ssearched for ages to find a script like this. I could not find anything for free. I did find one other good script but it was available under license from an American company and had huge ongoing costs. However, with the LuckyZoom script, the price is once only per website and you can use it on that site forever. Top marks to LuckyTeam.
