    If you only need 1 random number per page load, then it'd be best to use PHP for this.

    <img src="img/<?php echo(rand(10,100)); ?>.png">

    In the example above, 10 represents the lowest random number you want returned, and 100 represents the highest. But you can change those numbers to whatever you want.

      What do you mean by "duplicate" numbers?

    You don't really want a random number if it must be unique. Any random number generator will repeat a given number eventually. Why not keep a little file on the server and add 1 to the value each time you need a number? That way the number will always be unique and never repeat.
