I used jQuery for http://westphotoinc.com
I really liked the interface plugin's slider bar, it works great and looks the same on all browsers, unlike browser scrollbars. I didn't use too many of the effects, but it's nice for a few of the pages where i need to toggle images based on the thumbs on the left. Eventually I want to replace coppermine photo gallery with a php/mysql + jquery photo management & ordering app of some sort. Is there anything out there already? I had to make some extensive mods to coppermine to let me talk to paypal and I nearly wiped out all but the viewing functionality (comments, smileys, additional user acct's, etc were superfluous).
