Today, I found some more online sites worth checking out.
This is an awesome site for Christian music from other believers. Many songs provide MP3, sheet music, chord charts and lyrics. I know I will be spending time on this site!

If you have not visited this site before, it has a large number of resources including, graphics, books, testimonies, MIDIs, directories of Internet Christian radio stations and churches, etc.. They have a lot of older (pre-1900) Christian images under clip art.

This is a site I ran into looking for Christian clip art / photos. It has a number of photos that you can use for free. They do not have a large number of them, but some do look useful!
