Hi @lafr,
I originally added my “grey man” to replace an (in my opinion) unattractive kangaroo avatar that was used by osTicket core for a user with no avatar assigned.

I failed to realize that this broke the new Gravatar options, so thank you for bringing this to my attention and also for taking the time to offer a solution.
I will have to review why I did this in the first place and I will possibly take your advice and revert back to how osTicket core handles this in a future osTicket Awesome update.
