I ran into an example of the thumbnail issue again today -- this time on a post from kbin: https://old.reddthat.com/post/19193476

The thumbnail looks like this in the HTML:

<div class="thumb">
  <a class="url"
     href="https://media.kbin.social/media/60/a4/60a45b8ff88b1b2e3a0f77b701feb323c5bbfb7ceeb75154ea7df5d6eea15ef8.jpg"
     >
    <div  style="background-image: url(https://media.kbin.social/media/60/a4/60a45b8ff88b1b2e3a0f77b701feb323c5bbfb7ceeb75154ea7df5d6eea15ef8.jpg?format=jpg&amp;thumbnail=96)"></div>
  </a>
</div>

Note that it's making a request to kbin.social with ?format=jpg&thumbnail=96 parameters in the CSS -- which results in the full image being loaded since kbin doesn't run pictrs.

The versions in use on reddthat (according to the settings page) are:

lemmy: 0.19.4-beta.7

mlmym: 0.0.44

This kinda looks like an issue between lemmy and kbin. The issue is present on the lemmy ui as well. The ?format=jpg&thumbnail=96 parameter being there doesn't have an effect here. The issue is the thumbnail_url is reported wrong. You can see that here. The thumbnail_url should be: https://kbin.social/media/cache/resolve/entry_thumb/60/a4/60a45b8ff88b1b2e3a0f77b701feb323c5bbfb7ceeb75154ea7df5d6eea15ef8.jpg We could try and use some regex to lookout for kbin images and rewrite the thumbnail_url, but it should probably just be fixed upstream.

Found this github issue which might be related: https://github.com/LemmyNet/lemmy/issues/3775
