Alt text: a picture of Spider-Man looking at a wall with the caption, “Everywhere I go, I see his face”. On the wall is a picture of the profile page for Lemmy user the_picard_maneuver.
I assumed it was something to do with lemm.ee's policy with federating images to protect against CP attacks, since everyone else who says they're having trouble is also from lemm.ee. I think what they're doing is just linking to the other instances' images directly, and maybe startrek.website doesn't like that?
I can see your lemmy.world account's posts just fine.
