hi all

can anybody tell why else is not working

Code:

<script type="text/JavaScript">
var screenwidth = screen.width;
if(screenwidth <= 1024) {
document.write('<img src="image.jpg" width="1000">');
}
else
{
document.write('<img src="image.jpg" width="1250">');
}
</script>

I think it is due to the 'screen.width' assignment.

Use an alert to display the value.

alert(screen.width);

Your absolutely right.
Javascript works on the document.
Javascript can only detect changes to the document.
And the document is being displayed by the browser.
Every time you load the document into the browser, the Javascript will run again.
Changing the resolution of your monitor does not reload the document into the browser.
So if you are resizing the browser, Javascript can detect that.
But Javascript can not detect the fact that you changed the resolution of the monitor.
And as you already know, Javascript can detect the current resolution of the monitor when it is reloaded into the browser.
