/custommap give <URL> <-/small/automatic/scale <float> - You can have maps that are original quality, 1x1, automatically adjusted on item frames or you can scale your image!
/custommap changeproperties <original/small/automatic/scale <float> - if you already created a map with a different scaling mode, you can easily change that typing this command and holding a map
/custommap giveurl - gives you the URL of the image on help map
/custommap fillitemframes <x1> <y1> <z1> <x2> <y2> <z2> <-/north/south/west/east/up/down> - this command works just like the /fill command, but it fills the terrain with item frames. You can specify what direction you want them to be placed or the command will rotate them automatically
/custommap help - gives you a list of all commands
Custom maps now have the lore saying how big the image will be, how many item frames you need, and how to use it
You can shift-right-click one of the maps to remove the whole image from the item frames
Bug fixes:
Bottom left corner of the map is now rotated correctly
A lot of optimizations due to maps causing huge lags
