Finder: png thumbnails

[BraveRobot]

Hi. Is it possible for me to view previews of images as the thumbnails of my pngs in finder? Thank you.

Could you restate that?

What? Fine, I'll write a sentence that makes sense...

When I am browsing png files in the finder using thumbnail view, I want to see thumbnails of the images instead of the Xee (my default image viewer) icon for each file.
