SDDM signon page did not show picture for userid AND MORE

SDDM_signon_picture.txt

I had been using SDDM back on Fedora 25.  It always bugged me that my picture I supplied in my userid settings was not showing up on the signon screen.  The reason it was not, is that SDDM does not use the same registry for pictures as does the rest of Fedora.  

  I fould the solution at the SDDM ArchWiki.

    https://wiki.archlinux.org/index.php/SDDM#DPI_settings

  The solution is to take a png file (I chose one that I know is 96x96 pixels) and copy it to:

    /usr/share/sddm/faces/kurtis.face.icon

  Had to change permissions:

    chmod 777 /usr/share/sddm/faces/kurtis.face.icon
  
A simple logout from the current desktop session now has my picture for my userid in the SDDM signon page.

To change the sddm background, edit this file:  /usr/share/sddm/themes/01-breeze-fedora/theme.conf.user

  Here is a sample:
    [General]
    type=image
    background=/usr/share/backgrounds/xmaslightball.jpg

NOTE: On KDE Plasma.  The lock screen is handled by KDE not SDDM. The background can be changed as follows:

  System Settings-> Desktop Behavior-> Screen Locking-> Wallpaper-> Open... button at bottom
