Android - setting marker icon after getting images using Picasso

Question

I am retrieving my images from a rest service using Picasso:

  void drawMarker (String imageName) {
        String imageLocation = "http://172.16.104.118//MyService/images/%s.png";
        Picasso.with(this)
                .load(String.format(imageLocation,imageName))
                .into(imageView);

    }

I want to set the retrieved image as the marker icon but it's only accepting bitmap,

marker.icon("HERE");

                mMap.addMarker(marker);
