Some members had asked me to comment on this because one of my areas of research is rock art, so I thought I'd chip in with what's known.
First... the set of photos is absolutly wonderful! Very few people document rock art sites -- and documentation is important since these things get
wiped out by time, dust, animals, and human tourists doing graffiti. It's gratifying to see a nice set of photos, and I wish he'd shown more of the
pieces he photographed.
I do wish, though, that he'd shown the unenhanced ones along with the enhanced ones. Photoshop bumped the red channels in those photos (when he did
an autocorrection to make the pictures visible.)
So what's known about this rock art?
The people who did it are called the "San" (you may have heard of them under the name, "Bushmen"), who are identified as the ones who did the
oldest rock art on the continent:

This site is still used by the people today.
So... what we have is what's known as a "multicultural" site -- something created very long ago but that has been occasionally used throughout
several thousand years (perhaps as old as 2000 BC... during the time of the building of the Great Pyramid complex at Giza, if you want a timepoint
reference).
www.dhushara.com... So if we have questions about interpretation, we have people whose ancestors created the
art -- people that we can ask, saying "what did your ancestors tell you about this?"

It's also a site for initiation into adulthood. Much of it appears to deal with their shamanistic trance dances:

As you can guess by now, the art is not of an alien abduction. Recent conversations with the San indicate that it may be a healing ceremony (and yes,
they do hold the arms of the person being healed.) The central figure is a woman, the two holding her appear to be men (since they generally don't
wear clothing, you can tell from the male genitalia.) If you look closely at the panel (midway down here:
www.dhushara.com... ) you will see that it's a much larger one than 4 figures. There's a man apparently spearing an
eland (important animal to them) on the lower right with something small next to him and a larger (and apparently newer) anthropomorphic figure on the
left that was also done by the San. The bigger figure may be blurring out other art.
The big "double head" image is simply the way they prefer to draw themselves. Several images show overpainting (newer art painted over older stuff)
such as this one:

Note:
You might have noticed if you checked all the links that they have a shamanistic tradition but also have a "great god/one god" tradition. The
shamanistic tradition is older, but recently many family members have started to move into villages and towns and missionaries have been working to
convert them to Christianity.
Anyway, the photographer took a wonderful set of pictures and I'm glad he made them available to us on the Internet. This site isn't visited often
and still appears to be in good shape in spite of its age. There is one book on it by Leakey, and it's being tended as a World Cultural Center, but
documenting it over time is still a very important task.
