Storing multiple image files in a dictionary

I'm relatively inexperienced in python and was writing a shooter game for a school project. I'm trying to de-duplicate some variables which hold images:

wavetransition=pygame.image.load("TransitionScreen.png")
wavetransition=pygame.transform.scale(wavetransition,(WIDTH,HEIGHT))
wavetransition2=pygame.image.load("TransitionScreen1.png")
wavetransition2=pygame.transform.scale(wavetransition2,(WIDTH,HEIGHT))
wavetransition3=pygame.image.load("TransitionScreen2.png")
wavetransition3=pygame.transform.scale(wavetransition3,(WIDTH,HEIGHT))
wavetransition4=pygame.image.load("TransitionScreen3.png")
wavetransition4=pygame.transform.scale(wavetransition4,(WIDTH,HEIGHT))
wavetransition5=pygame.image.load("TransitionScreen4.png")
wavetransition5=pygame.transform.scale(wavetransition5,(WIDTH,HEIGHT))

these images are used as transition screens between levels in the game. They are then called in a random.randrange() variable:

rander=random.randrange(1,4)#Just For These Numbers To Redefine
if rander2==1:#The Random Backgrounds Displayed On The Wave Screen
      screen2.blit(wavetransition,(0,0))
if rander2==2:
      screen2.blit(wavetransition2,(0,0))
if rander2==3:
      screen2.blit(wavetransition3,(0,0))
if rander2==4:
      screen2.blit(wavetransition4,(0,0))
if rander2==5:
      screen2.blit(wavetransition5,(0,0))

is there any way to make this appear 'shorter'? Thanks
