Try a more web development forum for help with e-commerse like
questions like this one. You're only going to get very scratching
the surface type answers here.

The image is using something called an Alpha channel. In paint
programs it could be an alpha channel or something called a 'mask'.
The channel/mask indicates how transparent the color pixels are.
The program you use to view the target probably doesn't handle alphas
- or -
The alpha is stored as a separate image and the program that uses the
target applies the alpha itself
- or -
The program determines what is alpha based on some specific color and
sets the alpha of the target that way.
Most often than not the picture has an alpha channel. If it's a png
then loading it into firefox or something should show the image properly.
