cropsy is a jQuery plugin for creating a draggable and zoomable cropper window around an attached image, similar to Twitter's profile image selector. Its name comes from the Staten Island urban legend of Cropsey. Coder beware.
$('#profile-img').cropsy({
max_scale: 2,
mask_padding: 40
});
A demo is available online showing how to use cropsy in conjunction with Fine Uploader. The easiest for is to instantiate a cropsy instance during the uploader's onComplete callback.
cropsy's only hard dependency is on jQuery. It also depends on jQueryUI's draggable and slider components, but these should be removed at some point in the future.
