Here are some links which I have found helpful for the study of African Religions:

Chidi Denis Isizoh's website on African Traditional Religions

Images of Dogon Artifacts

Images of African Artwork
This is from a study guide for a course in African Artwork.  Just click on the links "Test 1," "Test 2," etc, to view the images from a wide range of African cultures.
