In shapes, replace the default texture files with these. You can copy and paste the default ones out just in case you want to re-use them, but make sure the new textures you put in are named the same way the default ones were before you replaced them. After you replace them with the new ones, highlight all of 5 them, right click, and click "Properties". Then, check the "Read-Only" box and hit "Ok" (make sure all of them are read-only!)
