I did some work for a client and had a few map designs for them to look at, I still have 4 left so I thought I would offer them to anyone that would like them.
this is an easy job, as the map is the SAME dimensions and SAME mapping as the original USA map given to us by the osClass Team

just upload the map to the image folder, (be sure to rename your original map to something like map.orig.png)
rename the map you uploaded to the image folder to just Map.png and thats it...
you shouldnt have to re assign the map in Admin as it is the same coordinates as the original.
Unless you havent used or assigned the map yet lol
we are real excited to get our shop open and show all you great members the stuff we have. Trying to finish up as soon as we can
