跨浏览器的jquery图片剪裁插件 A Image Cropping Plugin for jQuery

[Jcrop Example]
Preview

An example implementing a preview pane. Obviously the most visual demo, the preview pane is accomplished entirely outside of Jcrop with a simple jQuery-flavored callback. This type of interface could be useful for creating a thumbnail or avatar. The onChange event handler is used to update the view in the preview pane.
