Cast Profile Pictures

I have very recently signed up for an ImDbpro profile (Louis Zygmuncik IV) and have added my film Unwelcome Guests and its cast. I have full permission to add profile pictures to my casts profile but cannot afford to buy more than one pro profile. Is there a way that I am able to add a picture to their profiles without paying extra so they can have a picture and not a blank slate? Id really appreciate it.
