This is not possible with javascript. You need to use GDLib or some other server side image manipulation library.

That's not correct actually, there is a lot of jquery plugins that allow you to manipulate images. In fact there is simple photo editors in jquery

It is possible. You can manipulate images easily using canvas element. Though it's not cross browser solution. But you can work around even that using iecanvas.

I didn't know you could do that, pretty cool. Too bad it doesn't work with IE.

Google a little bit more. You must do this server side and ajax the results to the browser.

Note that this depends on a modern browser that supports the <canvas> tag.

If your audience have modern browsers you can use the <canvas> tag.

I'd say your best option here is to use something like flash, java, etc. JavaScript MIGHT be able to do this, but it will never be able to do it WELL. It is better to use a technology that has the power to do what you are asking without being stretched to it's limit.
