Do you use Privacy Badger or another blocker?<p>The markup loads images from seemingly local URLs:<p><pre><code>  http:&#x2F;&#x2F;data.simonschreibt.de&#x2F;gat055&#x2F;intro_comic.png
</code></pre>
but redirects to images stored at SSL-ACCOUNT.COM:<p><pre><code>  https:&#x2F;&#x2F;ssl-account.com&#x2F;data.simonschreibt.de&#x2F;gat055&#x2F;intro_comic.png
</code></pre>
I reset Privacy Badger, and the assets loaded fine.
