Getting height and width of things

[Anon]

I would like to know how to get the screen size (height and width) of the current document. I have a document which I want to be shown in different ways, depending on the browser size.

I also want to know if there is any way to chek the height and width of an image. And if there is, I want to know if it is possible to check the height and width of an image not loaded in a document.

Is there anyone who at least understand what I mean? 😉

use javascirpt for first option ie -

var w = screen.width
var h = screen.height

(if you search around you will found loads of scripts for this, you can easily set it so that various things happen for differing screen sizes. ie different page or different frame layouts etc)

and php for image info ie

getimageinfo(IMAGE)

fine for both methods, check out the user manul for usage on getimageinfo

Can I then transfer the JavaScript-info into a PHP script instead?

Use this code:

global sw;
if (!isset(sw)) {echo '<script language="JavaScript">'."\n";echo 'window.location = "'.$linkbegin.'"+window.innerWidth+"'.$linkend.'" '."\n";echo '</script>';
}

To have the window width set by the browser into the variable sw. The first time this loads, it will have to reload the page. But then you can hang onto the sw variable on the server side for the entire rest of the session.

Obviously, more adept javascripters can add conditional code for IE. This only works with netscape/mozilla.

I hope this helps.
