Maybe you heard about the new album from The Black Keys. Maybe you didn't. In any case, I don't want to talk about the album (which is good BTW), I want to talk about the album cover:

The Black Keys - Turn Blue album cover

See how bad it looks? Now click on the image and see how good it looks (in terms of quality, the album cover is pretty ugly anyway :P). The thing is, this stupid pattern is very hard to compress, so even using a JPG quality of 90%, you get a quite big file size and a pretty crappy image quality (126KB for a 500x500 image is quite a lot, 294KB for PNG using compression 9). If you look at the big image, even the colors are different, so the image makes resizing algorithms also go nuts, the image looks darker (or is this just an ilusion because of the changed relationship between both colors?).

Try it yourself, download the image, resize it, save it with different formats and qualities.

Coincidence? I guess not.
