In this case, yeah, it'll be better to post a link of the image hosted in another service, this way you also help the lemmy servers to not fill their disk so quickly.
I don't know about the Website/pc.
On jerboa, I can post images, and they get hosted on the instance where my account is.
However I can't find a way to post gifs, or videos. I could maybe be instance dependent?
I however created an account on a peertube server to share videos here.
It's not well integrated in the posts, as the user has to go to the website where it's hosted, but for now there isn't really other solutions.
