Here's how to change it to something better:

// set this near the beginning of your program:

Ext.data.validations.presenceMessage = "Required";

This widget shows an ExtJS Panel and Image component, along with the JQuery DeepLiquid JCrop widget, which allows you to select a crop area on an image.

Try it out by dragging your mouse over the image. You can also move the "crop" around.
