What happens if you open one of the image URLs directly in your browser? It's likely that it will show you some PHP error messages, maybe because of some include issues.

It might help to insert the following four lines at the beginning of the script that generates the images:

Code:

error_reporting(E_ALL);
ini_set('display_errors', 1);
require_once 'PEAR.php';
PEAR::setErrorHandling(PEAR_ERROR_DIE);

Thanks for your suggestion, but it still not workable.It showed me the following error message:

Code:
Warning: require_once() [function.require-once]: URL file-access is disabled in the server configuration in /home/xplus/public_html/PEAR171/PEAR/docs/Image_Barcode/docs/examples/test-image-barcode.php on line 45

Well, you seem to be using URLs (http://...) in your require_once calls. That isn't allowed on that server and it wouldn't work, anyway. Using the original calls is the right way. You maybe need to adjust your include_path.

I have reinstall PEAR in the server(web hosting server) and I have added the
Code:
error_reporting(E_ALL);
ini_set('display_errors', 1);
require_once '/home/xplus/public_html/PEAR/PEAR.php';
PEAR::setErrorHandling(PEAR_ERROR_DIE);
before generating the barcode. At this time, it didnt say any error message but it still cant show the barcode just like the first picture of this post.


I am wondering that if there are any problem with my PEAR. It is because i didnt follow the instruction after the installation as follow.

Quote:

To use PEAR without any problems you need to add your
PEAR Installation path (/home/rk2trade/public_html/PEAR)
to your include_path.


I didnt follow the above message because i dont know how to include_path in a web hosting space. Laughing

Yes, the include_path is indeed important. Possibilities are php.ini, httpd.conf, .htacess or your own scripts (PHP function set_include_path()).
