getting code instead of page description on picture

I am trying to make some changes to a website that someone set up for me then flaked out and doesn’t run for me. I’m managed to figure out a good bit, but this one has me stumped. I simply changed a picture on on my “Equine Facilitated Services” page and all seemed fine. When I went to the parent page. “services”, though, and scroll down to the bottom, it shows code below the picture instead of the description on the page like it does for all of the other services on the parent page. I think it’s an “appearance” issue but I’m not sure, and I’ve tried a few things that haven’t worked. Please advise…
