Feature/srcset thumbnail

Wouldn't it be neat if the thumbnail images could also provide a srcset?

Because the gallery has dynamic "fixed width" images that are calculated and recalculated according to the browser width, and also because the gallery uses media queries to change the container width, your solution would not work without using the 'sizes' attribute. For example if the image had a width="100" it would load the size relative to the width of the entire viewport instead of the smaller size needed. You can read further here:

I will research the issue a little further and implement an srcset and sizes option.

For sure. My implementation is fairly naive, but I did notice that Chrome was choosing the correct image to display.
