What's the best way to upload a picture to lemmy?

I've heard some servers struggled or even had to shut down because of storage costs. But that was a while ago, so it may not even still be a thing anymore.

There's the option of posting images to third-party services (like imgur or whatever), but I've been frustrated with not being able to see third-party images when scrolling the feed in Lemmy apps.

What's the meta right now?
