The primary photo is different for the overall episode list and individual episode

@mbmb​ Yes seems to be an issue. Thanks for bringing other examples to my attention!

@Fran​ Here is the episode - it has the correct image for the episode, but the wrong one when viewing 

Individual episode (correct)

All episodes (it's episode 7) - wrong thumbnail

I checked and these episode list display images were incorrectly categorized as a "Poster" instead of a "Still image". I have applied the changes and will live on the site shortly. The images should be the same in some minutes.

Not sure why they would be that way. Thanks for the help! This one is now correct! I have other ones I want to re-designate as the poster. Do I have to delete those and re-upload as "poster"? And if so, how? I don't see a way to delete any images, or re-designate as poster

As mentioned in my reply on the other post, for episodes stills are the poster of of the episodes. To change the category you would have to remove them and add them again. 

But what's confusing is that is allowed me to designate them as posters, however they werent used as the poster, other images I uploaded (as stills) were used as the poster instead. So you are saying I need to designate all stills as still, then choose as poster? I also don't have the option to delete any images. It's not given as an option

This is the reason why they were not used as poster, on Episodes Stills are used as posters and is the normal way to work. You can submit a request to IMDb to remove an image by using the  option listed at the bottom of the image viewer. Usually the title will automatically set up a Poster for it, if images are already added to the title.

@Fran​ thanks for explaining. Not sure why it gives me the option to choose poster when uploading if that's not what it's for, not very intuitive, would be good to add this info to the FAQ. 

@swoody26​ If something is a poster it can be uploaded as a poster, but it can't be selected as a primary image (for episodes), only still frames can be selected as primary, a poster should not be uploaded as still frame, it should still be uploaded as a poster, but it can't be selected as a primary image for an episode. Likewise, if something is a still frame, that should not be uploaded as a poster, it should be uploaded as a still frame, and since it's a still frame, it can be selected as a primary.
