Add title and button for each gallery image.

Hello. Would somebody be able to help me with some custom code please?
I want to place a title, plus a button over each corresponding image in Gallery > Slideshow: Full.

On my homepage I currently have placed a full bleed image section, with a title and button positioned in the bottom left, how I'd want them placed in the slideshow. Like this:

However, I want a slideshow of a few images with title and clickable links/buttons, instead of just one static image.
