When a caller (like Linda Kendall) does not have a picture in their caller profile,
it looks like they are not at an event with other callers that do have pictures
(take a look at our entry for Extravaganza as an example). Maybe we ought to
have a placeholder icon like FB and all the other places to show another caller?
HARD TO DO SINCE CALLERLIST IS LINKED WHEN EVENT RECORD IS SAVED
