Hmmm, poked around last night, and I don't know how to fix it. The comment pics are visible through kbin, don't know why they won't show up on Lemmy. I'm avoiding posting any more Imgur shorts for similar issues. Thanks for letting me know!
If you load the federated link it'll load from kbin.social. you'll be able to see, but won't be able to comment. I'm hoping these federation issues clear up soon
