Online Image Editor

We are looking to create an online image editing tool to provide additional functinoality to an existing website. We have a service which allows users to upload their own pictures to produce a custom flash video. We wish to provide the ability for users to perform small edits to the images that they have uploaded. These small edits include: - Cropping - Colour (Brightness/Contrast/Sharpness) - Colour pre-sets (black and white / sepia / etc) - Mirror (horizontally/vertically) The application should accept an image uploaded by a user and then pass the finished file back to our upload system. We will provide the design for the project as a set of simple image files which you should then replicate with flash. Please reply with samples of your work.
