Change Loading AND veiw mini map screen???

anyways, i have two problems... what format file do i need to replace loading screen file and how do i change the picture on the veiw minimap screen while u are waiting in a hosted game chatroom

Loading screen is complicated, and I don't feel like explaining it now. I'll wait for someone else to come along. But for the minimap image, you need a Targa (.tga) file imported into the map with the path war3mapPreview.tga.

Loading screens are actually made up of four different files, each a part of the overall image. I have attached below the Undead melee loading screen pieces so you can edit them. Once you have edited them, convert them to .blp format and then import them into your map and give them the following path:

UI\Glues\Loading\Multiplayer\FileName.blp

To make the screen appear, make everyone's race equal to Undead, as this uses the Undead loading screen paths.

Question, those files are really.. really.. big. Obviously you can't even host that on battle.net since it's twice the allowed size, so my question is that once they are edited and converted to blp, it goes down to a really tiny size right?

If you go to the tutorial section, there's an article on how to make a 100kb loading screen, I'd recommend doing it that way
