Sharing a link vs posting the media

Hi there, new to lemmy. Just want to find out whether its fine to share from mastodon or other Fediverse services to lemmy?

As opposed to uploading the media directly into lemmy and not needing to open it in another app / browser?

I ask as I post photos on say pixelfed or mastodon or Friendica from a one-click-share-all app (croissant app)

But is it seen as bad to then just share the link with the said media into lemmy instead of posting it as an original post made and posted in lemmy?

Any feedback would be greatly appreciated. :-)
