lol.
Why not do it yourself,it takes 2 minutes.
1.Go to the skybank\natural\Ngt folder and open all images in Paint,Gimp,whatever
2.Make them all with black solid color (you could also consider making them 1x1 pixel,so they don't take up space)
3.Save them over the original ones,but don't forget to back up the Ngt folder first
Or you could save them in a different folder and just copy the .X file over to the new one.
