Thank you for mentioning IrfanView. Back in the day I used to have a cracked copy of LviewPro that was always one of the 1st programs to be installed whenever I started working on a new system. It was small, fast, and I could easily flip through all the image files in a directory.

I stopped using LviewPro probably 8, or 10 years ago, but always wished I knew of a replacement that was so efficient. I see that IrfanView also does quite a bit more. I think I have a new favorite!

Now, if you'll pardon me, I need to drop the author a kind note. :)
