Hi Wade,
James example worked just fine.
<?php
header('Content-type: image/png');
$img = imagecreatefrompng('hotlink.png');
$col = imagecolorallocate($img, 0, 0, 0);
imagestring($img, 5, 4, 1, "circlecity.co.uk", $col);
imagepng($img);
imagedestroy($img);
?>
The image handle is all that's needed in imagepng();
It's the imagestring($img, $fontsize, $xpos, $ypos, $textstring, $col); that
you would put your text variables in.
You'll want to use your own font, as the max size is 5 in the default text
font, which is fairly small.
Once you get it working, you can add some variables to be passed to it, as the
text may overlap certain things in the images. Left, center, right, upper,
lower (you have to calculate them yourself) and maybe different light and dark
colours.
You can use getimagesize($img); to get the mime type and $attr is really handy.
It's all in the downloadable PHP manual.
As mentioned previously, you'd need to check if the image exists.
Bob.
