Picture as a placeholder

I would like to add a placeholder picture of a user, in case there is no picture added.
I now used a Display rule: If X is blank -> Display icon.
It works but the icon is (too) small.

Is there a way to use a certain picture as placeholder (like for example a caricature), when there is no picture uploaded?

Hey @Peter

@lee posted this solution using a Pipe. Would that work for you?
