Provide overview of the next slides

I've been thinking, when you one of the images from the gallery, we've got left and right arrow to use only. What if we add the possibility to have thumbnails on the bottom of the page?

I'd like to contribute and develop it. What do you think?

Hi Robert. The reason I made this was because I wanted a lighter, more minimal alternative to heavier lightboxes. I'm hesitant when it comes to adding more optional features because I don't want this to turn into one of those.

I appreciate you offering to contribute here and for #11 and if you make pull requests I will definitely check them out. But again I'm not sure it fits with the original goal of the project.

Alternatively, if you want to fork this and build some cool stuff on top of it I will definitely link to it in the readme. You'll probably have to refactor the code a bit to make it easier to add on to.
