I wouldn't use it for advertising as kyu has suggested, but just to add some hints and tips for new players not to leave this game after their first view at it.
Will each map have its own loading screen, or will it always be the same pics? and if its different pics, there should be the map name in big letters somewhere in the screen ![Tongue :P](Smileys/dp2/tongue.gif)
I wouldn't make a screen like this for each map, because there are hundreds of maps and it's quite impossible to have it like this.. Maybe there could be some screen from action related to hints and tips..
For example: Theres a screen showing how someone's flying through the window in shazam33
Hints & Tips: Learn to gain your speed with strafe jumping to enable faster movement and jumping. More info at "asdasd"
And it would be the same with DJ, picking up better guns, etc..
