Julien Lecomte at Yahoo! has written a YUI-based image cropper widget that allows you to easily select which region of an image you’d like to crop. This widget works on all A-grade browsers in both standards mode and quirks mode.

Once you setup the CSS and JavaScript you simply:

new YAHOO.widget.ImageCropper( "myImageId" );

Julien has further discussed implementing a scriptable XPCOM Component and an iPhone version of Y! Search.
