Client-side javascript/jQuery cropping an image + PHP processor

Very slick "area select" on-top of images plugin for jQuery. You can use it in your projects to create image "tags" or "tooltips" like Facebook does, or Flickr does even better. As usual for jQuery awesomeness, this is pretty easy to integrate.

And here's somebody that shows a validation processor in PHP that can crop the select area and save as an image.
