why do some YouTube videos on lemmy have a thumbnail, while some don't? (lemmy.world)

If you go to [email protected] and scroll you'll see some of the posts have a youtube thumbnail image, but not all.

I wanna post YouTube videos, but no one seems to engage much without a thumbnail, which makes sense, but I'm not sure what would result in the post actually having a thumbnail

If anyone has advice or guidance I'd appreciate it :) Thanks!

EDIT: so far it seems like it's potentially a combination of what version of lemmy the posters account is running, and how that instance is configured...

U can configure ur instance to proxy thumbnails so u cant just scoop up ips from users directly. Youtube imposes strict rate limmits on ips hence if some wont load. I assume idk for certain tho.
