   If you put this batch in the autostart folder, you can   
   use an old Laptop as a digital picture frame. After   
   power on, it displays the pictures in the directory   
   %p% in a fixed order (not random), but starting at   
   a random position. If you switch on the Laptop every   
   day at nearly the same time, you will always see the   
   same pictures. I wouldn't call this "random enough".   
   Therefore the otherwise meaningless line:   
   set r=%random% %random% %random%   
      
      
      
   @echo off   
   :: timeout /t 10   
   set p=d:\test\tmp2   
   set iv=D:\Programme\IrfanView\i_view32.exe   
      
   cd /d %p%   
   set n=0   
   if exist list.txt del list.txt   
   for %%i in (*.jpg) do (   
      set /a n=n+1   
      echo %p%\%%i>>list.txt)   
   set r=%random% %random% %random%   
   set /a  n=%random%*(n-1)/32767   
   more +%n% list.txt>list1.txt   
   copy /b list1.txt + list.txt   
   %iv% /slideshow=%p%\list1.txt
