Custom minimap crashes

Basically i have a custom image which im using to replace my minimap.

Personally I would rather use a smaller size to save space.
However it crashes the game if used in any size or than 256x256.

Yeah, so?

The thing is that a 124x124 image is supposed to work.

however here it is not.

Don't you mean 128x128?

yes i meant 128x128.

Which doesnt seem to work either in my case.

I'm not sure if you're talking about in-game minimap or minimap preview. Either way, if you're using .tga files then look into converting from rgb color to indexed color. It's a two second process in photoshop, not sure about other programs. It saves a shitload of space, and you'll get a 256x256 that is smaller than 128x128 but looks uncompressed.

Actually I managed slove it by changing it into a Blp.

But thanks anyway.
