The page http://www.packagekit.org/pk-screenshots.html loads quite slowly for me. Perhaps the Coral Content Distribution Network (http://coralcdn.org/) could be used for the screenshots.
To access something via Coral just add .nyud.net to the hostname, I tried and http://www.packagekit.org.nyud.net/pk-screenshots.html loads faster.
Just adding .nyud.net to the img srcs would do it.
I've thumbnailed the images, as I agree the page is too huge. New look age can be found here: http://www.packagekit.org/pk-screenshots.html
