I occassionally use PhotoSwipe when I need an image viewer (<a href="http:&#x2F;&#x2F;photoswipe.com&#x2F;documentation&#x2F;getting-started.html" rel="nofollow">http:&#x2F;&#x2F;photoswipe.com&#x2F;documentation&#x2F;getting-started.html</a>). Bit of a pain to implement, but I really like the way it works both on desktop and mobile and the fact that it has linkable URLs.<p>For all the over the top options that ViewerJS seems to have, I find it strange that a simple &#x27;click background to close&#x27; option is missing.
