// Consider something... related to your quiz ...
for ($i=0;$i<9;$i++){

      echo  "\n  banner284_files/GZKPICS_0$i.png <br>";
}  



/*   What do you need to do when there are more than 0..9; say 0..15; or more ?
      Well YOU HAVE OPTIONS:

         a) if-stmt
         b) ? : operation

         printf using %02d for the integer 
                the 0 (zero) will front pad number to exactly 2 digits!
                 tias!
         for ($i=0;$i<13;$i++){
           printf ("\nbanner284_files/GZKPICS_%02d.png <br>",$i);
