Samsung SCH-A890

I just bought this phone... I may or may not turn it in for the new LG 8100. For now, is there ANY ANY ANY possible way to put a different picture on the sub / front screen, other than the yuuuccckkyyy Preloaded ones there already?... when I go to change the wallpaper for sub LCD, it automatically opens the preloaded folder and gives me no option to choose from my own pics. Thank ya in advance!
