gnome-web-photo & php

[icsbcn]

Hello,

 

I have implemented this script:

 

<?php
shell_exec('gnome-web-photo -t 0 --mode=thumbnail -w 512 -s 256 http://www.google.com /tmp/google.jpg');
?>

 

If I execute it in the shell it runs perfectly, but if I execute it in a browser I view this error: Cannot open display:

 

Somebody can help me please?

 

Thank you so much.
