Evan, I always check your deletion proposals before approving them, and I periodically do find them with photos, etc, and I move those before approving the delete. So I don't think we've ever lost anything.
But yes, requesting the images be moved is best.
In the off chance that a comment is present in the doomed plant entry, if you wish, it would be good to just add a note in the deletion request to alert me to the presence of the comment so I don't overlook it. I can move the comment before approving the deletion.
