Good tutorial, although I was expecting the use of M2's for 3d rendering. For this image: http://gyazo.com/daf55fd27eff4ddd621707f093eda43b.pngUSE JPG's!!111!It's -huge- (file size). There is no need. You do not need a super high quality or an alpha layer or any of the functionality PNG supports. Just use JPG which will reduce the file size to around 200-300KB maximum. Bandwidth is a limited thing.
