You can't. What you can do is to figure out what area of the image the
text occupies and define that area as a hyperlink using an image map
(image maps are defined in HTML). But you will have to do it OUTSIDE
the script that generates the image.

1. Create a new image with imagecreate().
2. Read the existing gif/jpeg image using imagecreatefromgif()/
imagecreatefromjpeg().
3. Copy that image into the one you are working on using
imagecopy().
4. Output the new image.

For more information, refer to the PHP Manual:

http://www.php.net/imagecreate
http://www.php.net/imagecreatefromgif
http://www.php.net/imagecreatefromjpeg
http://www.php.net/imagecopy
