That's because edited or enhanced images of any kind don't belong in the main thread(if you were wondering why). if the person doesn't have a thread for edits they stick them there
If it is cleaning an image up or making clothing more see through that I don't understand. But like full on photoshopping, deepfaking, and AI yeah that I can understand not wanting in the main thread.
Generally if someone drops a small edit as a comment to point something out I'll just leave it in the comments. Same if someone posts a screenshot or vidcap to point out a certain part of a video clip.
Any edits or screenshots that are separate posts completely don't belong in the main thread. It just encourages people to repost or modify stuff for cheap likes. If it's worth talking about it might get moved to the discussion thread.
