As far as all of those pics...do you have alll of those browsers on your computers? I was recently tring to test a site on mulitple browsers and I came across a free tool http://browsershots.org
I've tried browser shots but I when I tried it there was a delay between submitting and receiving the images. Also they only give an image of the page so you can't test if everything works as expected. Sometimes links stop working and other funky stuff happens that you can only test with a real browser. I do have all those browsers installed.
