Images not displaying when clicked on

I was reviewing our site today and updating captions on the image gallery for each page as we build the site. When I went to the third property page on our site I get file not found when I click on the first image there. I am confused because the all the pages have the basic URL of this

https://aaarrrgh.business.ecu.edu/s16s/7/index.php/properties-3/

Where it differs is the page name for instance

https://aaarrrgh.business.ecu.edu/s16s/7/index.php/properties-3/c-street-b/

I looked at the first two pages and those have an additional slash and the picture internal name

/h3_5-2/ for those galleries

The third page and on I am not sure where the gallery is pulling from as after the 7 its trying to reference the images. /7/h2_11/

I did delete the gallery and reinstall it but its doing the same thing. I am starting to think its the images itself as some work fine when I create a test page and some from the other pages don’t. I created basically 5 different galleries so why the difference in the path
