If I upload an image into a post, it will appear on the post as well as the home page feed. If I create a second post and insert the same image from the media library, it appears in the second post, but not on the home page feed for the second post. It's as if the feed is not capable of displaying the same image twice. Can't seem to find it in the theme's code...
Example Post containing an "original" image:
(the thumbnail for this post appears on the homepage)
Example Post containing a second instance of that "original" image:
(You can see on the homepage that the thumbnail for this post doesn't appear... both posts use the same image from the media library)
Any ideas? I would like to avoid having to upload 100's (eventually) of copies of the same image just to have the thumbs appear...
