 All posters defined in the Metadata Files are stored in the [Plex Meta Manager Images](https://github.com/meisnate12/Plex-Meta-Manager-Images) Repository and all Overlay images are in the [Configs](https://github.com/meisnate12/Plex-Meta-Manager-Configs) Repository at [PMM/overlays/images](https://github.com/meisnate12/Plex-Meta-Manager-Configs/tree/master/PMM/overlays/images), which allows for changes to be made in one central location that will deploy to all users of this setup when they next run PMM.

Users of the [develop](https://metamanager.wiki/en/nightly/home/kb.html#how-do-i-switch-to-the-develop-branch) and [master](https://metamanager.wiki/en/nightly/home/kb.html#how-do-i-switch-back-to-the-master-branch) branches will only receive updated Defaults files when an update to Plex Meta Manager is released - this helps to protect to keep these branches stable and prevent bugs from reaching the wider user-base.
