People who upload are given the option to choose whether an image is an actual photo or source, like a document or headstone. A lot seem to miss that line on uploading. I usually just sift through a few pages worth when I have the chance rather than try to get through them all, as there are a lot. Hopefully, people will start using the "source" choice when uploading, which will keep the photos from ending up in the new photos feed for nominations.
