It's a picture of people taking a selfie. I think that communicates what a selfie is better than an actual selfie.

The caption says, somewhat ambiguously, "Example of a selfie".

That could mean "this image is an example of a selfie" (which is false). Alternatively it could mean "this image shows an example of a selfie being taken" (which is true).
