title: Python - error: couldn't open .png file
body: <p>Not sure what I did wrong, I am following a tutorial on how to make a game with Python and PyGame and I get the error:</p>
  
  <pre><code> pygame.error: Couldn't open resources/images/dude.png    
  </code></pre>
  
  <p>My code is as follows:</p>
  
  <pre><code>import pygame
  from pygame.locals import *
  
  
  pygame.init()
  width, height = 640, 480
  screen=pygame.display.set_mode((width,height))
  
  player = pygame.image.load("resources/images/dude.png")
  
  while 1:
  
      screen.fill(0)
  
      screen.blit(player, (100,100))
  
      pygame.display.flip()
  
      for event in pygame.event.get():
  
  
          if event.type==pygame.QUIT:
              pygame.quit()
              exit(0)
  </code></pre>
  
  <p>The full error message is:</p>
