Image Detection

[sharkey182uk]

Hey because im using css to create a layout which has a banner which always has to be 100% in width this is ok at 1024786 but at 800600 it cuts part of it off. So even if you use width:100%; at 800600 you lose quality. I was wondering if there was a php way to detect if the resolution is 800600 then give this banner if not give the 1024*786 banner.

Any help is greatly appreciated.

PHP can't directly, but JavaScript can. You can then have JavaScript pass the info back to PHP. But you'd have this:

user loads site -> JavaScript determines screen width/height and sends request back to server for PHP -> PHP works its magic and send new page back

The user ends up making 2 page calls for this to work. If you have a splash page, then this is fine. If you don't, then you'll need to get creative (such as just making it a JavaScript solution instead of a PHP one).

Hey thanks for the quick reply ok ill work on a pure javascript version so you dont have to load the page twice. I just wanted to know if PHP could do it becuase if users have javascript turned off wud be a bit innaccessible.

Thanks again anyway

If the user has JavaScript turned off, you wouldn't be able to autodetect the screen width/height. The best you'd be able to do is provide a spash page with links or a form to the various versions of the site.
