If you click the “i.redd.it” part of the Lemmy post it’ll take you to a Reddit page containing the image which has the user’s account on the bottom left. You can even view the original post from this page. I’m using the lemmynsfw web interface for this. Does that help?
Unfortunately adding a note would require more effort than I’m willing to put in.
Just paste the Reddit link the description? Doesn’t seem like much more work.
