Easily Add Captions To Feature Images

I was looking for a way to display captions below feature images. I tried another plugin available for just this purpose, however it did not work correctly and was last updated over two years ago. FSM Custom Featured Image Caption not only works to display captions on feature images, it also provides additional options for enhanced customization. When I had a support inquiry, Fesomia replied quickly with an explanation about the notices I was seeing (while in debug mode) and a minor update to their plugin.
