I am call the piechart.php file from within the chart.php file. But when I try to view the file in the browser

 

For IE is a cross mark in the img

Whereas in Firefox its is just a blank page.

 

I have GD library installed and using Windows XP and WAMP.

 

Can any one help me on that.. Its urgent...

Well for starters. Your code is wrong for the HTML, It puts an X because it's invalid markup!

 

"<img src="[localhost]; "

Needs to be

<img src="http://127.0.0.1/chart.php"/>
