(i think there was not requested before) 
:-TileImage(#Image,Width, Height) to convert #Image to same but tiled to reach that Width and Height.
-CropImage(#Image,Width, Height) to cut out image to become that Width and Height.
-Or maybe TileCropImage() (or wahtever name) to do both things in one.
I've noticed ResizeImage() rinses the image each time is called, and it is too slow for PB.
