Vista is perfectly capable of understanding and displaying .png files.
I just confirmed it by converting a .jpg to a .png in Photoshop and
both Windows Explorer and Photo Galley open the file and show it find
as both a thumbnail and in full view. It is true you can't "fix" a
..png from Photo Gallery. Why that's so, you'll have to ask Microsoft.
For those wondering about .png files, it carries a Alpha channel. This
means that with the right software (Photoshop for example) you can
mask a portion of the image, typically some unwanted background, mark
A color or selected area as transparent then using another application
that supports layers have the Alpha channel blocked out, in effect
letting what's underneath bleed though.
