This plugins is based in the tag cumulus but shows the photos of the profiles instead of the tags.

In the setting you can define the colour, width, height, size, and quantity of photos you want to show.

When you click in one of the photos it forwards to that person's profile.

There is an example where you can see it.

Here some screemshots:
