I just spend the last couple minutes trying to view that picture and had nothing but issues.
It first opened in the imgur app, but there it only showed a zoomed out preview which I can't just zoom in on, I need to click to open it again larger but then it wouldn't let me zoom past a given point. So I uninstalled the app, re opened the link and it loaded in their web UI, which had the same issue as the mobile (can't zoom enough). I then long pressed the image, opened it in a new tab, had to modify the URL to remove the "fidelity=medium" in the URL, and I could finally view the image in my browser and zoom in on it...
