The photo shows a display of simit (Turkish bagels) stacked high in a glass case. The caption above the simit says "Ne olursan ol ama insan ol (No matter what you are, be a human)". The joke is that simit are often associated with poverty or being a "poor man's food". So, the caption is a humorous way to say that even if you are a simit, you should still be a human being.
