I like jQuery. I like it a lot. So much that I've taken to writing plugins for it whenever I get the chance. Said plugins can be found on this page.

• Gallerax (a flexible gallery plugin)
• Formerize (easily add inline labels to form fields, even passwords!)
• Slidertron (a flexible slideshow plugin - coming soon)

All plugins are dual licensed under the GPL and MIT license, so pick your poison.

PS: You may have already seen or used these in some of the templates on Free CSS Templates. To save bandwidth we don't include all of the plugin docs/examples with each template, so if you find yourself wanting to tweak a particular plugin's behavior just download it from here to get the whole thing.
