An image of professionalism is vital no matter what type of business you own. By posting your photo at the SFI Affiliate Center, that professionalism is on display for your PRAs logging into the Affiliate Center. Consequently, using icons or pictures of pets, children, and others may only serve to distract from your business image.
That's why we at SFI strongly recommend you use a nice, clear photograph of you for display to your referred affiliates. In this way, you can begin to build a business relationship with your affiliates, and they can see that a real person awaits to help them.
