It was very helpful! Thank you very much. The only thing is that

$r = ($rgb >> 16) & 0xFF;

$g = ($rgb >> 8) & 0xFF;

$b = $rgb & 0xFF;

didn’t work in my case. I’ve changed it for

$r = ($rgb >> 16) & 0xFF;
$g = ($rgb >> 8) & 0xFF;
$b = $rgb & 0xFF;

@Morlacheerful,

The demo is working as far as i can see. Go to http://blogoola.com/ and click “show map” then simply click on any country and that colour is mapped to one in the database and performs the JavaScript redirect.

If you go directly to the code for the page: http://blogoola.com/js/javascript-animations.js you will see the AJAX image map section which has the code for the demo. The code for the PHP side of things is posted above in the article.

Hope this helps.
Sam

Hi,
is it posible to get a working demo?
i can not get it to work, but the DEMO link does not work, so i can not check what is wrong, or if i forgot something to setup.

Would be nice if someone could answer me with a workling DEMO link.
Kind Regards.
