trying to get an image gallery to work for a mobile device, but it says to implement the files that i downloaded.

it says this for a folder i downloaded

How do I use it?

PhotoSwipe is a self contained JavaScript library that can be easily integrated into your mobile websites. It is heavily optimized for mobile webkit browsers. However, if you need wider desktop browser support or you are using jQuery Mobile, PhotoSwipe comes packaged with a jQuery implementation as well.
