Black listing is never secure. White listing is. Sadly some really smart person decided it was a good idea to store pictures and SSH keys within the same directory tree.

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";
    };

~/Pictures and ~/.ssh are as far apart as they can be while staying in the user's home directory. I guess you could stick stuff in... /var or something, but that seems worse overall.
