Post photos missing from blog

I recently noticed that some photos are missing from a few of my blog posts. My blog is [ redundant link removed ]. At first I noticed some featured images weren’t visible, so I re-added a bunch of them and they now appear, but when I dug down into my posts I notices that a few have missing photos. I confirmed the photos are still in the ‘edit’ post and in my media library. Also, I just finished writing a new post and when I preview that post some of my photos are missing in the preview. I can’t post this latest until all photos are showing. Any idea why my photos disappearing?
