See my screen captures.
You can request these photos be removed through help chat at https://wayfarer.nianticlabs.com/new/help where you will find the photo issues under the abuse category rather than the edits section. In my experience, they will not remove the only photo on a Wayspot, so be sure to add an extra photo to these if they do not have one.
Hi, @cornelwest. We have taken another look and decided to remove the invalid image for the Wayspots in question.
