Thanks for the reply.
I've attached a mockup example.
I'm comfortable with adapting the css of the gallery navigation to get just simple 'next', 'previous' and 'slideshow' symbols. Where I hit a brick wall is when it comes to the titles/descriptions. I want to get a symbol button that when clicked ON, the photo description will appear and when clicked OFF they will disappear. (See images)
Any help you can offer will be greatly appreciated. All the best,
