+The directions here are what I followed to turn my raspberry pi and 7" pi screen into a photobox.
+**Step 1 - Setup **
+Install Raspiberry pi OS (full) onto an SD card and install in your Pi.  Bootup, run raspi-config, and get everything setup the way you like it.
+**Step 2 - Screen **
+Follow directions [[https://www.instructables.com/Raspberry-Pi-Touchscreen-Setup/|here]] to setup the screen
+**Step 3 - Mount network drive on Pi**
+As discussed [[https://access.redhat.com/solutions/448263|here]] edit
+  /etc/fstab,
+add the line:
+  //192.168.1.110/public/photos   /diskstation_share   cifs  _netdev,username=guest,password=,dir_mode=0755,file_mode=0755,uid=500,gid=500 0 0
+note that _netdev is needed for network shares.
+also, i followed the instructions here [[https://askubuntu.com/questions/1081601/how-to-fix-fstab-samba-mounts-not-loading|here]] and created the file
+  /etc/network/if-up.d/fstab
+with the lines
+  #!/bin/sh
+  sleep 30
+  sudo mount -a
+Note that the sleep command is a hack that allowed the Pi to settle its network connectivity before it attempted to mount the network folder
+**Step 4 - Slide viewer **
+following the directions [[https://www.raspberrypi.org/forums/viewtopic.php?t=199320|here]], I created the file runslideshow.sh on the ~/Desktop with the following lines
+  #!/bin/sh
+  cd /home/pi/diskstation_share
+  feh -Z -z -F -D 300 --hide-pointer --auto-rotate --recursive
+Note that the recursive allows the directories to be searched recursively.
+To make sure it autostarted correctly, I followed the directions [[https://learn.sparkfun.com/tutorials/how-to-run-a-raspberry-pi-program-on-startup/method-2-autostart|here]] and created a .desktop file at /home/pi/.config/autostart that contains
+  [Desktop Entry]
+  Type=Application
+  Name=runslideshow
+  Exec=/home/pi/Desktop/./runslideshow.sh
+**Step 5 - Schedule screen dimming **
+To schedule screen dimming, open the scheduler with
+   crontab -e
+and add the following lines
+7 * * * sudo sh -c "echo 255 > /sys/devices/platform/rpi_backlight/backlight/rpi_backlight/brightness"
+21 * * * sudo sh -c "echo 12 > /sys/devices/platform/rpi_backlight/backlight/rpi_backlight/brightness"
+which brightens the screen at 7:00 and dims the screen at 21:00.  Note that 255 is max brightness and 0 is minimum (off).
+**Step 6 - Enable right click as a long click **
+Modifying the directions from [[https://fmirkes.github.io/articles/20190827.html|here]], run the commands
+   sudo apt install build-essential libevdev2 libevdev-dev
+   git clone 'https://github.com/PeterCxy/evdev-right-click-emulation.git'
+   cd 'evdev-right-click-emulation'
+   make all
+   sudo cp 'out/evdev-rce' '/usr/local/bin/'
+   sudo chmod +x '/usr/local/bin/evdev-rce'
+Then navigate to ~/.config/autostart, create the file: evdev-rce.desktop, and fill it with
+   [Desktop Entry]
+   Version=1.0
+   Type=Application
+   Name=evdev-rce
+   GenericName=Enable long-press-to-right-click gesture
+   Exec=sudo /usr/local/bin/evdev-rce
+   Terminal=true
+   StartupNotify=false
-from [[https://access.redhat.com/solutions/448263|here]] edit /etc/fstab, add the line:
-//192.168.1.110/public/photos   /diskstation_share   cifs  _netdev,username=guest,password=,dir_mode=0755,file_mode=0755,uid=500,gid=500 0 0
-note that _netdev is needed for network shares
-also, i followed the instructions here [[https://askubuntu.com/questions/1081601/how-to-fix-fstab-samba-mounts-not-loading|here]] but added a pause 30 line before the mount -a.
