ok, but the article says that there is more images (btw, other media too), i.e. images make 50% of web page now and image size growth contibutes ~400KB out of ~900KB, images tend to change, given that top 1000 pages are dynamic, thus, no cache will help. Also I find it interesting that stylesheets are growing, given that css3 are more powerful now and IE6 is likely to be retired for most of these sites. What is interesting is what makes this "other" part? is it just webfonts or some media (also very cross-site cache friendly)?
