I don't know javascript, but I took this script and made changes by trial and error. I have made modification that can work for most sizes - 14x14, 21x21, 28x28, 35x35, 49x49 and so on. I will like to upload the script but I will like to give my thanks to the owner of this script for such a nice original big map. Can you please tell me how to thank the owner of a script in another modified version of the script?

for a long time searching utility for the map. This one is more convenient to work, beautiful. If the developers will add size 14x14 or 12x12 - I will be grateful
