When remove a picture from a detail page, it still shows up on the list page

Hi, I added a table, then put a photo into the content of a detail page. The table and photo was later removed from the detail page, but the photo/table still shows up on the list page, not the detail page. I want it removed from both pages. How do I get rid of the photo from the list page?

Here's a link to what I'm talking about: http://www.mtgrovecemetery.org/bulletin_boardList.php There is a photo on this page, the list page. I removed the photo from the first link in the list. It's gone from that detail page, but is still present on the list page. Why is that?

Many thanks![;)]
