showing image title as captions under image in 7.1 galleries

Hi i would like to show the image title as a caption under the individual images either in the Grid;Masonry or Simple Slideshow gallery styles (the latter also has thumbnails under the single main slide show image). However I hadnt realised before signing up that version 7.1 galleries dont show captions.

Is there a way to add code that does this to specific galley pages rather than site wide?

thanks
