PHP call program by exec on Linux

I have a php program running on CentOS and require to call firefox using exec for plug-in activities, however it seems the system did nothing while calling the command by exec (e.g. exec("firefox -saveimage http://www.yahoo.com")), I'm sure the command can run thru terminal, is it related to rights issue?

I have find some documents about "sudo" but no help... can you guys help to list out a detailed steps for such setting? Thanks a lot!

firefoy is unable to start and execute any command if there is no X-Display reachable. You will either need to run a local xserver and enable the localhost to connect to the X-Server so firefox can contact that screen. The run the the command like:
exec("DISPLAY=:0.0 /usr/sbin/firefox -saveimage http://www.yahoo.com");


replace :0.0 with the correct display no
