how to check weather user profile is present or not

Hi All, 

I have a condition where I want to show a user profile photo if it is there otherwise show initials. 

For Image , I am using a!Image and for Initials I am using a!stampField. 

Can i use these two together so that if user profile is not present than I can show Initials.

Thanks In Advance,

Saurabh
