That's right, this is probably the easiest way to add tooltips to your site. What I really like about this is that you can add a tooltip a link and when you hover over it you will see a screenshot of that link.

In some browsers like FireFox when you click a link you will see little dotted lines around it. Some website designers don't like to see this. It doesn't really bother me but some day it might so just in case this can be fixed easily with a nifty little plugin for jQuery. Its called jQuery Link Scrubber and can be found here.

If you looking to spice your site up a little you should consider using some jQuery plugins. Here are some that I like. Magnify Magnify allows you to easily create a "magnifier" on your images. You just need to create a small and large image which are proportionally sized, configure your markup accordingly and let Magnify do the rest.
