PhotoSwipe needs update
You already have it in jsdelivr repo - https://github.com/jsdelivr/jsdelivr/tree/7f4b5cef6dc27ff764d400c5f05edeb00e7735bf/files/photoswipe
But the new version of PhotoSwipe was released a few months ago, it has the new repo that is located here: http://github.com/dimsemenov/PhotoSwipe
Files that it requires are in folder dist/ https://github.com/dimsemenov/PhotoSwipe/tree/master/dist
Would be great if you edit it.
