The new gallery weblink style is dark, you can also edit the CSS in wl/css folder to customize as you wish, I just did it for my server.

I second this, I have added photoswipe on many websites, it works great on mobile and desktop.

I had this same problem, one line fix in /wl/css/gallery.css or folder.css add this line at the end

.actionBtn:not([href*="path"]) {display:none;}

hides "download all" button on the main link page when there is not a 'path' in the URL!
