BTW, you might not be concerned about it much, but you have a race condition in your script.
Ave,
What do you mean by "race condition" ?
If more then one user is accesing the page, you might overwrite the first one's verify.png image. Simple and sufficient solution is to append a random string to the filename:
$image_filename= 'verify_' . md5(rand()) . '.png'; ImagePNG($im, $image_filename); ?> <img src="<?php echo $image_filename; ?>" width="200" height="40"> <?php
Just remember to add some way to remove old images.
