I am trying to make something that allows a user to upload an image, and then shows them 8 different thumbnails from different parts of the image(like 50px by 50px per thumbnail), and they can choose one to represent the image. Then both the regular image and the new thumbnail are copied to a directory and put onto the site, the thumbnail linking to the larger image. I have this as an idea, but I don't know PHP well enough to understand what functions I would need to use, so any help would be greatly appreciated.
