Basis for creating a monster image showing its health:

<?php
 
	$img = imagecreatefrompng("beetle2-tiny.png");
 
	$grey = ImageColorAllocate($img, 204, 204, 204);
	ImageFilledRectangle($img, 70, 30, 20, 10, $grey);
 
	$black = ImageColorAllocate($img, 0, 0, 0);
	ImageString($img, 3, 25, 10, "HP:100", $black); 
 
	header('Content-type: image/png');
	ImagePNG($img);
	imagedestroy($img);
 
?>
