Why can’t I expand images and videos beyond this arbitrary border?
That’s more of a Mlmym problem than a Lemmy problem. Every frontend tends to handle images a little differently.
I don’t see an open issue for that problem, yet, though, so might be worth putting one in for the developer to work on.
If you want to go back to reddit because of that, then you never really left reddit
Can you clarify what you mean by that? It sounds strangely gatekeepy to me, but maybe I’m misunderstanding
I don’t use imgur for posting pictures on Lemmy like I used to on Reddit. Am I supposed to?
Use Connect for Lemmy.
I used Boost for reddit for years, so I switched Boost for Lemmy as soon as it became available. It’s not free, iirc it was $3 or $4, but it works well and I’ve had zero issues with it.
