Sprite looks washed out on site

[eldomtom2]

I originally posted this on the Ripping Help forum, but realised it would be better placed here. I hope reposting it here isn't against the rules.

I am ripping the sprites from Chris Sawyer's Locomotion. When I rip them, the image looks normal.
   
But when I upload it to the Spriters Resource, it becomes washed out for some reason.
