Hi, Thank you for your concern. Actually they are not removing the air dates and not removing the previous/next episodes, they are still there in edit mode. They must be editing the format to cause it not to show up. I'll be fixing them.
First you save the image to your computer and make sure you name it something like JounryBeyoundSodorPoster3. Then you uploaded it here: Once thats done, you go to the Gallery page for JBS and find the "Promotion and Marketing" section and add in for example if your image is named: JounryBeyoundSodorPoster3 you add it on the page as: File:JounryBeyoundSodorPoster3. (Also make sure you also include the file format (png/jpg/jpeg, ect) And that should do it! :)
