I saw that each event created in the calendar was given it’s own single page (like a post would be given it’s own single page). I could add the picture on the single page and then pull the image out and place it on whatever page/post I wanted with some php.
The computer I’m using to code the site is not with me at the moment and naturally I don’t have a repo or anything like that, sorry if my explanation wasn’t very clear. if you need more explanation I can be more specific next time I’m at work.
best of luck
