How do you import MINIMAP images without getting a blank image?

How do you make custom minimap images?

I've tried it before but I've always gotten a white screen, even though i've changed the path name of the imported file.

How do you do this successfully?

It probably has the wrong dimensions, it can be 64x64 or 128x128.

use w3m Map Ultilities to import a mini map

for a custom minimap:

dimensions: 256 x 256
type: .tga
path: war3mapPreview.tga

then it should work :D
