Uploadify client side resize / ActionScript

This project description is easy to understand. I need client side re-sizing before image be uploaded. This upgrade need to be made on [login to view URL] uploader. Re-sized image must don't loose image quality. Must work on jpg,jpeg,gif and png files (also transparent) . JavaScript control parameters like max-width value. Dont post "template" comments. You need to know ActionScript/Flash to do this work! (Twice i post this project, and ppl are trying to resize with javascript or similar..)
