If you go to !videos@lemmy.world 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…

    It’s because Lemmy can’t fetch YouTube thumbnails. I swear it used to fetch thumbnail and title automatically before, hmm

      It’s because YouTube puts a bunch of JavaScript at the start of the file (1MiB) before the opengraph tags and Lemmy only fetches the first 512 KiB (a fix was merged a couple days ago).

        If you don’t put a whopping 1MB of JavaScript in your website, you’re doing web development wrong.

          Don’t forget to add also the 2856 partners intrusive code lines and cookies to have a “better experience”

      I can testify to this. I was there. I was there when Lemmy so valiantly fetched ye old YouTube thumbnails.
