Dear all,

I migrated from a very old Piwigo version (11.5) to version 15 so far.

I can access Piwigo and I can see all the albums, but no image show up. I've noticed that the default location initially moved from ./config/www/gallery/galleries from /gallery (from inside the container).

It means the below former docker-compose is no more valid:

```
    volumes:
      - /mnt/docker/piwigo/config:/config
```

But should be :

```
    volumes:
      - /path/to/piwigo/config:/config
      - /path/to/appdata/gallery:/gallery
```

That being said, can you please validate the following approach would be a good option to fix this issue?

Move the current galleries folder out of /config to /path/to/appdata/gallery.

Create volume /galleryto point to the new location.

Re-create the stack.

By the way, I don't know if the Admin/Tools/Updates should be used or not, since I'm running on Docker.

Just need your insight for the best option !

PS : I did a full backup of everything, so no big risk ;-)
