PNGs are not needed unless there is transparency. Takes up a lot of time for not a lot of quality improvement.

Okay I'm sorry! I've just seen you replacing some of the wallpapers that are originally JPG to PNG from the PSD. If you want, you can replace this with JPG, I would do it but I can't because I'm not admin here.
