PHP Image functions -- help

[Hemanth]

Hello,

Could anyone throw some light on the following questions, please?

1) How can I add a hyperlink to an image file generated using GD
library?
For eg., I'm using ImageString(... ) function to add text to a JPEG
image. I want to make that text an hyperlink.

2) How do I insert another gif/jpeg image into an image generated using
GD library?
For eg., I've the following code......I want to include "test.gif" into
the generated JPEG (something like <img src=''> in html)

header("Content-Type: image/jpeg");
$c = ImageCreate($cw , $ch);
:
:
ImageFilledRect angle(....)
ImageRectangle( ....)
ImageString(... .)
:
:
ImageJPEG($c);


TIA,
Hemanth

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 imagecreatefrom gif()/
imagecreatefrom jpeg().
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:
