Not able to click on a post image on the post detail page

In pull request 780 we implemented a Photoswipe library to make it possible to make the image bigger.

This library works fine on the post teaser in the streams, but does currently not work for the post detail page where you get this error after clicking on the image:

js_FBEpSrvAR1BvqZgsWbA2Dd4SHdi83iib1GOI_JBndcU.js:3889 Uncaught TypeError: Cannot read property 'split' of null

    at HTMLDivElement.i (js_FBEpSrvAR1BvqZgsWbA2Dd4SHdi83iib1GOI_JBndcU.js:388

Solution

Currently the image is linking to the original image, causing a double link:

<div class="photoswipe-gallery" itemscope="" itemtype="http://schema.org/ImageGallery" data-pswp-uid="1">
     <a href="/sites/default/files/23.jpg" data-med="/sites/default/files/23.jpg" data-med-size="800x400" data-size="800x400">
       </a><a href="https://distro.getopensocial.net/sites/default/files/23.jpg">
 <img src="/sites/default/files/styles/social_post_photo/public/23.jpg?itok=rDGvnYqp" width="714" height="357" alt="23.jpg" class="img-responsive">
</a>    
 </div>

We need to change the default display mode to not include the link to the image anymore.
