  az egy program, shell scriptből így tudod használni.

  Na ez így még mindig nem mond semmit azon kívül, hogy írjak egy scriptet, de googleben találtam scriptet, ami működik. [link]

  #!/bin/bash
  
  #################################################################
  # Script to select a random wallpaper in GNOME 2 #
  # #
  # Selects images from the previously selected wallpapers, #
  # and from a desired folder. Its path should be configured #
  # in line 31, along with desired image extension #
  # #
  # The script also selects the rendering method for the image #
  # This feature uses the command "identify", from ImageMagick #
  # Also, check if your distro is using gconftool or gconftool-2 #
  # Change this option in lines 50, 52 and 56 #
  # #
  # The Delay between images is set in seconds, in line 62 #
  # #
  # Create an entry to this script in your "Startup Applications" #
  # to execute it in every gnome session start. The command would #
  # be: #
  # PathToScript/background.sh & #
  # The & would run the script as a background process #
  #################################################################
  
  # Begin of infinite loop [condition always true]
  while [ 1 == 1 ] ; do
  
  # Create array with the filenames of the previously selected wallpapers,
  # from the information in the file "~/.gnome2/backgrounds.xml"
  ALIST=( `grep filename ~/.gnome2/backgrounds.xml | sed 's/<filename>//g' | sed 's/<\/filename>//g'` )
  
  # Add to this array the filenames of images '*.JPG' in "$HOME/DATA/Pictures"
  # folder. Additional folders could be added with the same syntax
  ALIST=( "${ALIST[@]}" `find $HOME/DATA/Pictures/ -name '*.JPG'` )
  
  # Obtain the number of elements in this array
  RANGE=${#ALIST[@]}
  
  # Select randomly one of these elements
  let "number = $RANDOM % $RANGE"
  
  # Obtain the width and height of the image
  xIMG=`identify -format "%[fx:w]" ${ALIST[$number]}` #Width
  yIMG=`identify -format "%[fx:h]" ${ALIST[$number]}` #Height
  
  # Compares the Width and Height, to select the rendering option of the image
  # If Width > Height, select "zoom"
  # Else, select "scaled"
  # Possible values: "none", "wallpaper", "centered", "scaled", "stretched", "zoom", "spanned"
  if [ "$xIMG" -gt "$yIMG" ] ; then
  gconftool -t string -s /desktop/gnome/background/picture_options zoom
  else
  gconftool -t string -s /desktop/gnome/background/picture_options scaled
  fi
  
  # Set the random filename as wallpaper image
  gconftool -t string -s /desktop/gnome/background/picture_filename ${ALIST[$number]}
  
  # Pause in the script, in seconds. The time the image will remain as wallpaper
  # 60 = 1 minute
  # 300 = 5 minutes
  # 1800 = 30 minutes
  sleep 300
  
  # Continue loop
  done

  Beraktam, hátha valaki másnak is jól jön. Persze ékezetes mappa nem jó a képeknek...
