How to get all photos from gallery?

Question

Gallery

Hello, I want to get all the photos from the device gallery, preferably in the grid, how can this be done. I searched on the Internet, not on Russian sites, not on foreign ones, there is no such thing.
I want to achieve: when a button is pressed, a certain animation container opens, and all the photos from the gallery are gradually displayed there (gradually, in my case, a certain placeholder will appear until the photo is fully loaded). Although, if it is possible to achieve the same selection from the gallery as in VK or Telegram.
