Thanks @a_5mith . Sorry for any confusion . Well, when you're looking at the home page whether logged in or logged out the "guest" pic is broken. Where it appears is if you click into the Category. For example, if I go to http://mynodebb and do not login the post shows a broken image, then if I login, and view the home page, the image for guest is still broken. However, if I click into the Desktop Support category, the image shows there (from within the category). The image with the gravatar address is coming in when viewing in the category.
