How do I show Salesforce User profile photo on site

Hi, I have similar issue. How do I show Salesforce user profile photo on site. If i use , it works on skuid page, but on site it does not display any image.

In Sites, you do not have users, there is no authentication. Technically, all visits to a Site are treated as being performed by a “Site Guest User” associated with each site. This user does not have a Profile photo. Therefore, I am not sure what you are trying to show.
