If you see a directory for pictures, it means XDG directories are available in your system. Then you can change their location at will, and place them as deep in your user directory as you like. Like in `~/opt/art/visual/picture`.

My Nix Home Manager settings for XDG directories:

    xdg.userDirs = {
      enable = true;
      createDirectories = true;
      desktop = "${config.home.homeDirectory}/var/desktop";
      documents = "${config.home.homeDirectory}/opt/docs";
      download = "${config.home.homeDirectory}/var/download";
      music = "${config.home.homeDirectory}/opt/art/music";
      pictures = "${config.home.homeDirectory}/opt/art/visual/picture";
      publicShare = "${config.home.homeDirectory}/var/public";
      videos = "${config.home.homeDirectory}/opt/art/visual/video";
      templates = "${config.home.homeDirectory}/opt/templates";
    };
