I added a default avatar that I designed via Illustrator. I placed it in the avatars root directory because I felt it didn't deserve a directory of it's own, or to be plaved in a directory created by another author? The code to point to the default avatar still needs to be updated. To be truthful, the default avatar should be placed in the default theme directory so that each theme used can have that option of using it's own default avatar. Just my 2 cents. Please move or rename this image appropriately.
