Bumped into something similar: When having Photon and Cloudflare enabled, images didn’t show at all. Disabled Photon and images came back, except for the ones at the bottom in the Related posts section. Found this topic here and I can confirm that Hotlinking Protection at the server level does indeed block not just Photon, but also images in the Related posts section. All good now and thank you for such a fine plugin!
