I know this is a popular topic but I'm 100% stuck on this one and hopefully someone will have a solution for this...
I'm using the Columnist theme, and what I want is a featured image on the main page so there's not just a grey box, but then when you click on the post what I DON'T want is the featured image to then appear AGAIN above the post, as all my posts are images.
As an example check on the first 3 posts in the list, the first post 'desolate' has no featured image set, yet still shows the preview on the home screen which is what I want as this doesn't show 2 images click you click on the post.
The second post 'Oxjam Manchester' has no featured image and as expected doesn't show a preview but the image is in the post as normal.
The third post 'Ants' has a featured image set, and as you can see it does show a preview, but then also shows it twice on the post itself which isn't what I want.
So from what I can make of this, it's the posts with the picture icon next to them in the list are the ones that recognise it's an image post and don't need a featured image added in order to show a preview in on the blog.
The problem is, I've checked all the settings on all 3 posts and they're all exactly the same. They were all posted from a laptop and clicking 'add media' to insert the image in to the post, so I don't understand what needs to be done differently to tell WordPress to show the preview without needing a preview image.
I know you can probably edit the code to remove the featured image on each one and keep it in the preview but I don't want to do that every time I post. There has to be something I'm missing when posting, help!
The blog I need help with is edduffill.com.
