find center of an image...

[mfacer]

hey..

I'm adding a watermark image on to any uploaded on my site. This all works perfectly, only I need some way of putting the watermark in the center of the image (at the bottom).

Is there some PHP function any one knows of that will be able to get my image (300 width x 50 height) to go right in the middle of the uploaded image?

Many thanks....

Math problem, not a PHP problem.

$x = 300;
$y = 50;
$watermarkx = 30; /width of the watermark
$watermarky = 30; /height of the watermark

the coordinates to put your watermark centered at the bottom would be
(($x / 2) - ($watermarkx / 2),($y - $watermarky))

or 135,20
