How do I Crop an image through Events?

I want to make a puzzle game in which the user uploads an image from their own computer, and then the game takes that image, cuts it into several squares, and shuffles them around. And while most of this is clear to me on how to do... The cropping of an image has me stumped. If anyone can help me find out how to do this, I would be very grateful.

In C3 you can do this with Drawing Canvas. Paste your image to multiple small Drawing Canvas objects, after that you can remove the image and re-shuffle the pieces.

It just... Won't work. I have a Sprite I upload a picture to. I have a Drawing Canvas I tell to paste the object from the Sprite to it. And... Nothing happens. I have no idea how to use the canvas
