How could a circle of circular images be created?

Question

I want to create a little image for some slides for the purpose crediting a team for some work. I want a set of images to be set around a circle path and each of the images to appear as circles also. How could I approach something like this?

Very roughly, what I'm looking for is something like this:

It feels like TikZ could be used for this in some way, but I don't know where to start.

Answer 1

Lot's of drawings of smiley faces in the other answers, but if external images of the team members were required, then something like the following could be used/adapted:

\documentclass[tikz,border=5]{standalone}
\tikzset{%
  image 1/.initial=example-image,
  image 2/.initial=example-image-a,
  image 3/.initial=example-image-b,
  image 4/.initial=example-image-c,
  image 5/.initial=example-image-golden,
  image 6/.initial=example-grid-100x100pt,
  path image/.style={path picture={%
     \edef\imagename{\pgfkeysvalueof{/tikz/image #1}}%
     \node at (path picture bounding box.center) 
       {\includegraphics[height=1cm]{\imagename}};
  }}
}
\begin{document}
\tikz\foreach \i in {1,...,6}
  \draw [path image=\i] (\i*60+30:2) circle [radius=0.5cm];
\end{document}

Answer 2

This can be easily done with TikZ and pic:

The code:

\documentclass[border=5pt]{standalone}
\usepackage{tikz}

\definecolor{myblue}{RGB}{24,97,170}
\newlength\Radius

\begin{document}

\begin{tikzpicture}[
hface/.pic={
\fill[myblue]
  (0,0) circle [radius=\Radius];
\fill[white]
  (0,0) circle [radius=0.85\Radius];
\fill[myblue]
  (0,0) circle [radius=0.75\Radius];
\fill[white]
  (-0.3\Radius,0.3\Radius) circle [radius=0.125\Radius];
\fill[white]
  (0.3\Radius,0.3\Radius) circle [radius=0.125\Radius];
\draw[white,line width=0.125\Radius]
  (-0.35\Radius,-0.3\Radius) arc [start angle=210,end angle=330,radius=0.4\Radius];
}
]
\setlength\Radius{1cm}
\foreach \Angle in {30,90,150,210,270,330}
\pic at (\Angle:4cm) {hface};
\end{tikzpicture}

\end{document} 

Placement on a circle is done using the polar coordinate system:

\foreach \Angle in {30,90,150,210,270,330}
\pic at (\Angle:4cm) {hface};

where (\Angle:4cm) is 4cm away in the direction given by \Angle.

\documentclass[pstricks,margin=1cm]{standalone}
\usepackage{multido}
\begin{document}
\begin{pspicture}(-5,-5)(5,5)
    \multido{\i=0+60}{6}{%
    \rput(!3.5 \i\space 30 add PtoC){%
        \pscircle*[linecolor=blue]{1.5}%
        \psset{linecolor=white,linewidth=4pt}%
        \pscircle{1.3}%
        \pscircle*(.7;60){4pt}%
        \pscircle*(.7;120){4pt}%
        \psarc(0,0){.7}{220}{320}%
    }}
\end{pspicture}
\end{document}
