Code:
<?php
//image headers
header("Content-type: image/png");
// random number 1-9
$num = RAND(1,9);
// generate image name
$myimage = "pic".$num.".png";
//create image
$im = imagecreatefrompng($myimage);
// output the image binary
imagepng($im);
//destroy image
imagedestroy($im);
?>
Like that perhaps.
