How to use the jrGravatar module to provide a default profile image?

restmin:No matter how nice your one default image is, it looks a bit boring and unprofessional to new members when they see 25 of these default images appearing. It makes it seem like people are not enthused to be there.
This is the point of the "require images" skin config option - only profiles with an actual image will show up on your "main site" pages - that prevents visitors from seeing tons of "no image" images. It works well for that purpose.
