So I ran across an answer to a question that was not much more than a couple of short sentences and the suggested edit was six paragraphs plus three images:

Hopefully that link works and shows the specific edit I was concerned about.
The edit feels like it just should have been a separate answer and not an edit of an existing one. Problem is I have no idea what you do in a situation like this. I skipped voting on the edit, but it kinda felt like that is something that should have been brought to a Mod's attention (but no way to do that), or am I overthinking this?
