Google map markers with rounded corners

Hi, looking for a solution to draw a marker as a rounded image on a dynamic Google map. I have a working map, with the markers as square profile image, looking only for the way of making it round.

Thanks!

Thanks, but this is for using symbols. What I need is to make a square profile pic to be presented as a circle, like the image I attached
