It’s scraped by your instance, so if Lemmy doesn’t return it then nothing is there.
But also, lemmy devs seem to always be tweaking the scraping so it’s possible it’s better, but Lemmy.world is running outdated version rn.
If I'm not wrong, images, like in every social, come from the page itself and are scraped (or not?) from the og:image or og:twitter
If you share any link and open it on desktop and inspect the page you can see at the beginning the og:image which is the same you see in the posted link. Example:
The link I sent above has this image and if you share it you'll see that image
I’ve used instagram links and kickstarter like this one.
And someone gave this for me to use on a lemm.ee instance, but it wouldn’t load on a lemmy.world instance. https://files.catbox.moe/qtxxrk.mp4 when I tried using the same website elsewhere
I just want to get into doing more posts, but I am confused on how to get consistent visual images to load on timelines from articles, general website thumbnails, gifs and videos.
I noticed thumbnails work better for youtube.com than their short url youtu.be, but I don't know if this is a Voyager issue. I think thumbnails are pulled by your instance.
That is also what I was reading, that each instance may have its own backend rules on how things are pulled. I worry that may become an issue with cross posting or probably deter people from posting in general if true.
