We are looking for an online image editing tool where customers can customize an image and then buy it. We have the shopping cart component. Here is an example of how it should look like: [url removed, login to view]
Once they have finish their design they would hit buy it button and the new image would be attached to the order.
The editor would have a predefined set of shapes, texts, and background colors to choose.
Also we would like the tool to be developed in ajax, jquery, mootools, php or other so long as it is readable by apple's ipad. Last resort would be Flash.
Any questions please let us know.
