Transparent PNGs do have transparent thumbnails now, they previously had black, but you will need to use this style to get rid of the white background behind the image:

.category-gallery-item img { background: none; } You may also want to throw a " border: none; " and " padding: 0; " in there.

And if you want it completely flat: " box-shadow: none; " and " -webkit-box-shadow: none; "
