I am trying to make a gallery page and I want to show all pictures from Media Library. All images are attached to different posts, so when I use: [gallery id=all], it doesn't show anything.
I have many posts, so I can't put all IDs from all posts one by one.
Is there any way to show all pictures from different posts in a single gallery?
Or how can I get all IDs in a fast way?
