Ps or Gimp and don't edit sizes.

I believe its height thats why theres so many. I never tested my
theory but one day i will.

BETER FORM TO EDIT:

With GIMP, edit the first image (there are 8). Notice that the collisions are partially transparent. Probably 124 not sure. Draw with a transparent blue to add colisions, or make it 100% transparent for no colisions. When you finish, the best form to copy 8 times is:

- make a 256x256 grid
- align to grid
- with square selection, select the first square
- ctrl+c
- new layer
- delete main layer
- ctrl+v to the eight squares
- done

NOTE: You can mirror the image at the start, because it apears reverse. Then mirror again when finish.
