Ok so I'm almost done with a website. The website is supposed to allow a user to upload a image onto a product. Then save the new image. I've got the upload function complete. The drag function complete. Which those two things work good. But I can't figure out how to use image merge, in PHP, to combine the images and save them. I know how to do it with set pictures but these are going to be random pictures that users upload.
If anybody could help me that would be much appreciated thanks.
