Tired of looking at that old DC3? Dreaming of Ireland? Change your splash screen! Just make a backup of your dlgsplash.bmp file in the Uires folder in FS9, rename one of my files "dlgsplash.bmp" and place it in the Uires folder. Bob's your uncle: you're looking at the old sod.
Or, use all the files with a splash randomiser, such as Geoffrey Schreiber's Splash Screen Randomizer v2.5 (ssr25.zip - download from FlightSim)
