Are there any good tools for converting .png or .psd or .jpg or .gif into .ico files? A free tool would be a feather in the cap.

ImageMagick should do it: use the convert tool that comes with it: convert -resize 32x32 logo.png logo.ico

If you want a (free) Windows GUI tool, IrfanView is one of my favorites.

IrfanView [irfanview.com/] has batch processing, so you can convert a batch of images to ico. –  gimel Oct 10 '08 at 13:10

I found Niall's png2ico very easy to use. It supports multiple resolutions in one ICO file and full alpha channel. It's free and for windows.
