k i have a question about the picture thing

now what im talking about is how people do the picture thing like when u dl a map off of b.net u see the picture and not what the map looks like. i would be thankful for any help

Its called a Custom preview image its not related to modelling at all.

If you want to do this in your map, import a 256 x 256 pixles 24bits .tga with the path: War3MapPreview.tga
Then its done.
