Seems like there are other Imgur submissions on Fedia that mostly work fine (no thumbnail, but the image itself shows up if you click on the expando thing in the UI) https://fedia.io/d/imgur.com
I did notice that at some point around the time of my second comment Imgur was having some issues (I was given a JSON file instead of a webpage or image when I found and clicked on the image that OP submitted), so maybe fedia and a few other instances just got unlucky with the timing?
If you notice it becoming a recurring problem you can report it on Fedia’s meta magazine/community: [email protected]
Minor bug in the UI / frontend I guess - you could try reporting it to the lemmy devs on GitHub if there isn’t already a GitHub issue for it
