Media Library slide show

I am working on a Neptune WordPress site and I basically want to display caption for each slide-show when you click on pagination navigation.

I want to use caption in place of <p><?php the_title(); ?></p>. I have gone through my code many times and I still can’t figure out how to do this.

Please take a look at https://imagedepartment.co.uk/demo/?portfolio=story-10 and I’m sure you will understand my problem from there.

Please I need help urgently!

Many thanks!
