Well, just changing the thumbnails to avoid resizing increased my Page Speed scores DRAMATICALLY. I am in the high 80's and even 90 on the home page. Now if we can just iron out the animation oddities we will be good! And honestly, at least on the iPhone, the thumbs still look pretty good (tablets look great as well)
@Kreisi - thanks for the tip on resizing. The only other issue I see is that IE8 looks odd (as I mentioned) and in Chrome the portfolio loads first in color and then flashes black, then fades in gray... so looks very jarring. Thanks for all the work on this.
