Note1: I design maps for 1280x1024 desktop so the entire map fits on my UI-View in full screen mode without scrolling bars (i hate map shift). If you use lower resolution like 1024x768 etc., it may be better to RESIZE the maps to fit in your window. Resizing does NOT affect correct calibration, so feel free to experiment...
Note2: Maps are stored with a decreased palette of 256 colors to become as small as possible. The PNG format is preffered.
