PNG is lossless compression so the image doesn't loose any detail from 
the original. But, you still have to have enough pixels to handle big 
images, e.g., if you have a 300 dpi, 300 pixel by 300 pixel image it 
will show okay at one inch by one inch printed out. On the screen with 
it will look okay at about five by five inches, screens being 72 or 96 
dpi devices.
