making transparent gifs

[Buzzard]

I know this probably belongs in computer thread, I just thought I'd get a possibly quicker response here. Mods, feel free to move it.
I have a couple hundred gifs that I need to make transparent for my website. Irfanview is a great little program that works well for doing that....one at a time! If irfanview can, I dont know how. Anyone know of a free program that can do them as a batch? Thanks!

Can you use the tool you're talking about from the command line? If so you could whip up a batch file to do them all pretty easily.

And I thought you just mis spelled the word gifts and were to cheap to buy them

A free demo of Paint Shop Pro can do it in a batch, but I'd recommend using .png files for transparacies...I think they look slicker
