Isolate Image from Post

Hey everyone. I’m building a site for a client and they want continuity between all their posts. All of the content from the posts in one area and the image that they choose to put in the post isolated to another area. I’ve figured out how to post the content without the image showing up in the area I’ve isolated it to, but I cannot for the life of me figure out of how get the image from the post and put it into a separate div / isolated area.

Thanks for the help
