I’ll start reuploading them to catbox then! I know that Lemmy.One, in general, is not all that reliable.

Thanks for the feedback.

EDIT: A few things:

1. I got all my old posts fixed now. Let me know if anything is not working.
2. Before fixing, if I viewed this community from my home instance of lemmy.one, the images on those older posts would not load. But viewing the community on its original instance of lemmy.world, it seems all those lemmy.one images had got cached on lemmy.world’s server and that is what was displaying there just fine. So I was able to just view the “broken” post from lemmy.world, copy the URL of the cached image, then edit the post back in lemmy.one by just pasting in that image URL. Now, those broken posts are all pointing to the lemmy.world image and working again, even when viewed on lemmy.one.
3. All of the catbox images from just my posts 2-3 weeks ago were also not loading, Even though you could open up the image directly just fine, they were not loading within the Lemmy post (on lemmy.one, at least). Strangely, I just had to edit the post to get it to start working again. Just click edit, make literally zero changes, then click save.
