Help with Bush in 30 Seconds Ad

Hey folks,
I'm trying to enter the Bush in 30 Seconds Ad contest (details at http://www.bushin30seconds.org). I had an idea for a mock gameshow of Name That President, but I couldn't get a camera crew together in time. So now I have to do something more documentary style with photos, stock footage, text and voiceover. If anyone knows where I can find the following, I'd be eternally grateful...

Photos or stock footage of...
A military funeral
Caskets coming home from Vietnam
A good picture of Bush in front of the Mission Accomplished banner on the USS Lincoln (the only ones I've found so far on the web have been too small)

Thanks.

PS: Is anyone else here entering that contest?

I had gotten a few of those already. It's tough finding ones that are large enough to use for video. Stock footage has been particularly difficult to find, though I'm still pouring through the thousands of public domain clips at http://archive.org/movies/ for something useful.

Best resource for political photos is the george washington university archives. Found that pic of Rummy shaking Saddam's hand in the '80's there.....

Best of Luck,
Teresa
