If I share someone else's photo on Facebook, will my friends comments appear on my post or the original?

...also why doesnt it appear in the newsfeed when I share their photo?

Just dont want my friends comments to appear on the original and want to make sure I can delete their comments if I need to

It is both... If they open the photo they comment on the original
if they just comment directly from their news feed it appears from your post.

it will Appear on the Original When you Share it you are adding a Whole New Photo so The Comments will Not Appear on the One That you Shared

Check your Posts Settings Make Sure you Dont Have it On Private as That would Prevent it From Adding

[Y U NO SHUT UP!]

If they click the photo,they comment on the original but If it shows up in their newsfeed and they saw it ,their comments appear on the shared one. You shouldn't worry about it...no one ever comments on the original.
