Basically I have a website where people can upload an image they want printed on a t-shirt and add it to cart. The upload utilizes an app and the image appears as an addon to the order called "Custom Image 1: IMG"
What I want to do is make a script that would take this image after they upload it, process it a bit and then show how that image would look on a tshirt.
For the record, I want this image processing to take place before they add the product to card. Right after they upload the image basically. Thanks!
