These
options allows you to load tiles of any dimension and virtually any file type.
The supported file types are BMP(*.bmp), JPEG(*.jpg|*.jpeg), PNG(*.png),
TIFF(*.tif|*.tiff), TGA(*.tga). However, there are some guidelines and it
should be noted that Map Maker bases all its information off of the first tile
it loads.
Filenames
must by <integer>.<file type>, where integer is > 0 and less
than 256, and file type is one of the supported file types.
