Do you think putting your photograph on a business card is good or bad?

I'm a realtor and I need to make up my business cards. Some have told me that putting my photograph on them can lead to potential clients not taking me seriuosly at first glance because I am young (umed that I'm unexperienced) and a women. But some say it helps ociate you with your company. I want to be taken seriously and if the way I look could prevent that I need to reconsider my photograph.
