Client-side image resizing with cubic interpolation?

I'm wanting to have a web interface for batch-uploading and resizing images to my server. I've seen quite a few solutions for resizing images client-side, most of them flash based. I really don't care what technology a client-side image r开发者_开发百科esizer uses as long as it:

1. Is reasonably fast
2. Resizes images with some sort of interpolation (cubic will do just fine)

Does anyone know of something that would be good for this purpose?

Hey, try this tutorial: http://www.mikesdotnetting.com/Article/95/Upload-and-Crop-Images-with-jQuery-JCrop-and-ASP.NET

It uses a jQuery plugin called JCrop.
