Facebook: text vs. image

How often do we add a caption to the photos we post on Facebook? Is the photo not enough to stand alone? I took all of the photos I have posted on Facebook and superimposed their captions, so they can battle between which is more important: the image or the text?

My Working Thesis

I am continuing on the work that I started last semester for my thesis. In this series, I used photos of my fiancé and I, who grew up in the same decade, in similar social and economic situation.
