That preview is way bigger than 400x300. You're gonna need to shrink it or stick it behind the cut (sticking it behind the cut and putting a smaller version outside of it works too!)
And man, this looks way too good to be Frank Miller. I'm inclined to believe he mostly did the breakdowns while Paul Smith did the actual pencils. I've had the hardcover to this series for, like, two years, but I've still never read it.
