Every time I go look up pictures from Vizzed.com Super Mario all stars for the SNES I look at the screenshots from the game. When I see the screenshots of the pictures they look all blurry as if there is a bilinear blur to them all. All of them are like that. However I copy that image and save it to my pictures. I go to my pictures on my PC and I zoom into the image I just copied. Wow! Amazingly their all extremely pixellated and blocky zoomed in all the way. Its as if this blurriness disappeared. Is this just the Internets resolution to all the pictures having some blurriness to them a little? If you do this you'll see what I'm talking about in Vizzed. Its strange.

Sounds like you are trying to view them with to high a resolution.
