Costum minimap preview

[Daminon]

I'm trying to get a costum mini map preview to my map and I know how to do but it won't work. I have read tutorials about this and followd them but when I choose my map in the game the mini map preview is all white. Why? Does anyone know how I can get it work?

There are only certain sizes that can be used... such as 192 x 192. Also they have to be the same width x height, and .png. See this website: http://www.wc3sear.ch/viewtopic.php?p=29510#29510
