ImageIO can't read my file? (input==null)

When I try reading the image from my res folder, I get this error:

Exception in thread "main" java.lang.IllegalArgumentException: input == null!
at javax.imageio.ImageIO.read(Unknown Source)
at SpritePractice.render(SpritePractice.java:103)
at SpritePractice.run(SpritePractice.java:71)
at SpritePractice.start(SpritePractice.java:123)
at SpritePractice.main(SpritePractice.java:131)

The image itself (MarioSpriteSheet.png) is in the res folder, and I spelled the name right. What's the problem here? 

BufferedImage spriteSheet = new BufferedImage(WIDTH*2,HEIGHT*2, BufferedImage.TYPE_INT_RGB);
    try
    {
    spriteSheet = ImageIO.read(getClass().getResourceAsStream("/res/MarioSpriteSheet.png"));
    }catch (IOException e)
    {
        e.printStackTrace();
    }
    finally
    {
        pixelsFromImage = ((DataBufferInt) spriteSheet.getRaster().getDataBuffer()).getData();
    }

Omit /res/ from the filename. If res is on the CLASSPATH you shouldn't need it.
