Don't Delete Images from the Gallery Due to Downvotes

There's been a tendency lately for people to downvote images due to lack of understanding about the topic presented, or a personal dislike toward the topic, despite the actual quality of the image. This causes perfectly good images to be lobbed out of the gallery because the users who would actually upvote weren't online at the time. So, the obvious solution is to not auto-remove images due to downvotes, but only for requests for deletion, for actually offensive/inappropriate images.
