Asp.Net web based Image editor

Hello Hardcore Asp.Net developers! I have an urgent requirement of an web based image editor where users can create images using admin defined tools. Something like photoshop but very simple. But the users must have the ability to save the file and later on edit it. Once they've finished editing, they can export the image into jpeg or any other format. For further details / questions, PM me. So, let's hear it, guys! Gim'me your best shot!
