Displaying PNG files in GM

I am trying to understand how this thing works:

when I open the icon in Windows Picture Viewer/ Paint / I have a good quality of the image. Clear lines, shapes and so on;

But when I open it in GM or Display it through a web-client using MapServer it gets really "pixelated", it renders really bad.

I am trying to find out why it does the processing on it. It appears as it renders in using an 8 bit quality, dunno. Before, using mapserver5, the same icons renders well, but now, it does look quite bad, like it is not sharp, lines are pixelated, colors faded, although the original image seems ok.

Do you have any idea why this can happen?
