Old Post Summary Image Still Appears?

Hi Team Virtue!

I’ve been updating Featured Images on my site and, for simplicity’s sake, keeping the same file names as I replace the photos.

For example:
– Remove a Post’s Featured Image
– Delete OLD Photo: ABCDEF.jpg from Media Library
– Then Upload NEW Photo: ABCDEF.jpg to Media Library
– Select the Post’s New Featured Image
– Save the updated Post

When I update the post’s Featured Image in the Admin, it then appears correctly on the front end when I refresh my web browser.

The problem is that the Post summary, displayed on a Category page for instance, still displays the old Featured Image, even though I deleted it in the Media Library.

I’ve dumped all my caches, etc.

What’s the best what to make the new Featured Image appear in the Post Summary?

Thanks!

Wes
