I know, this is a bit OT, but since I'm pretty
sure we've all got humongo image collections,
I thought I'd throw out a couple I use quite a
bit since Thia brought up the contact sheet 
generator.  ACDSee 32 is a great program for 
quickly viewing thumbnails of images in a 
directory. You should be able to pick it up for a 
download  at www.shareware.com.  Another one I 
love for taking screen caps from DVD or VCD on a 
computer is HyperSnap DX.  They are at 
www.hyperionics.com.
Just thought I'd share.
