How to place text under picture in gallery?

Hi again.

Got a small problem with my gallery again:

Is there a way to place the text, share button and other info underneath the picture/film?

I simply want the picture or film to be on top and all other info underneath.

Would also be good to know what template you use to edit the gallery part of the website, in case more problems like this occur?

Thanks for the great help so far!
