Free Folder Switcher?

I changed my default folder image setting using the trial of Candybar, but now my trial has expired and I'm kind of sick of all of my folders being wood grain. I suppose I could just go in and manually replace the icon, but I'm wondering if there is a less messy and less time consuming solution.

I'm hoping for either an application that will let me switch the folder default or at least reset it to default.

Many thanks in advance.

Nothing free except LiteIcon and a commenter says not to use it in SL.
Try the demo of Icon Box to reset your icons.
