Changing the campaign screen.

I saw a trigger that something along the lines of "Game- Change Campaign Screen" Nearly every level I have I want the campaign screen to change to more suit the storyline or opponents of that map... Yet this trigger seems to have absolutly no effect and my campaign screen does not change at all... Do I need to save this change in game cache or something?

No one has any information on this?

I don't think it is possible. It might be a trigger just for Battle.net tournaments or something, like that Tournament trigger, i believe is under Game.

So its not possible to change the campaign background screen on your map list mid campaign? Cause I want the background to reflect the upcoming level.

Thats what the loading screen is for.

Yah well, I have no programs to convert images into the format used by loading screens and the default loading screens are extremely lacking, most of them are just map screens from campaigns... The generic one is lame, pretty much been stuck using the "Credits" loading screen, only decent one I could find for my campaign out of the default ones.
Hence why I want to be able to change the campaign background screen between levels... Or import my own loading screens, but as I said, I have no program to convert images into blp's, or how to properly import them and I've seen NONE available for download.
