hey so I am not the creator of this but you can very much so do so! When you add it to gamemaker studio 1 or 2 then click to the top of image button and then go down to edit image size i believe and on the bottom left of that new panel is the dimensions of the photo. so if you change that to 64 and 64 it will scale to that with the canvas as well! this may sound complex but if you really just read it and pay attention to what i said it should be fine! this is a bit late but i hope this helps!!
