Jcrop is a powerful image cropping engine for jQuery. It's been designed so developers can easily integrate an advanced image cropping functionality directly into any web-based application without sacrificing power and flexibility (or the weeks of coding, testing and debugging). Jcrop also features clean, well-organized code that works well across most modern web browsers. Here you'll find the documentation for Jcrop itself. This guide assumes that you have a basic knowledge of HTML and including files into a web page. At the end of the article, there are links to more advanced concepts and implementation techniques.
