For example:

   for K = 1 : 15
     filename = sprintf('Output_%02d.jpg', K);
     surf( rand(5,5) );   %some plot
     drawnow();
     saveas(gca, filename)
   end

That is, you can compute the filename that you pass to saveas(). In the above example, %02d means to output as an integer of at least two digits using leading 0's if needed to make two digits -- so 01 then 02 then 03 ... 09 then 10 then 11 and so on.
