image size for a popup window

[zapster]

Hi,

Is there away in finding out the size of an image in Javascript?

The reason why i ask is that i need to create a popup window with an image in. But the image changes every day and i don't have control on it size. What i would like is for the popup window to resize itself (hofully via javascript) to the size of the image.

Can this be done, if so how

Thanks

you could assign the image an id, then get its width and height and resize the window accordingly
[tt]
<img id=&quot;myImage&quot; src=&quot;image.jpg&quot;/>

<script language=&quot;javascript&quot;>
var i = document.getElementById(&quot;myImage&quot;
// add 10% to compensate for window borders, toolbars etc
window.resizeTo((i.width * 1.1), (i.height * 1.1));
</script>
[/tt] =========================================================
while (!succeed) try();

Thanks Jeff

That works Great

is there a way to find out the source (url) or the name of the image

i.e. if blank.gif is loaded i can close the window down as this would mean there is no popup window was required.

thanks once again

yes - use imageObject.src
[tt]
<img id=&quot;myImage&quot; src=&quot;image.jpg&quot;/>

<script language=&quot;javascript&quot;>
var i = document.getElementById(&quot;myImage&quot;
var src = i.src;

// add 10% to compensate for window borders, toolbars etc
window.resizeTo((i.width * 1.1), (i.height * 1.1));
</script>
