Details: When creating a custom mood theme, the user should be able to add pictures for custom moods. For example, the user might want to have a picture for "sarcastic". The user can upload the picture and bind it to the mood, and hen the user types in the cutsom mood "sarcastic", that mood icon appears.
Pros: More flexibility.
Cons: Less standard. Will only appear correctly on users journal and on friends journal if user doesn't over ride friends' mood themes with their own.
