Image Caption (right justification)

Does anyone know what code is needed to make image caption to appear below image with right justification?

Did you ever get an answer to this?  I am trying to do the same thing

Wexley image captions in slideshow, this comes up a lot. Here is some old code, hope it works for you. I have one site built on Wexley myself.
