Problem with a gallery-script

[klofisch]

Hello,

I tried to use the following script. I think i got it from php-resource.net

The problem is, i want to open the images in a popup by Javascript.
I change this Line

[code]  <a href='$current_dir$pic' ><img src='image_resize.php?i=$d$pic&w=$w&h=$h' alt='$pic' />[/code]

to this

[code]<a href='$current_dir$pic' onClick="return popup(this,790,651)"><img src='image_resize.php?i=$d$pic&w=$w&h=$h' alt='$pic' />[/code]

but without any success:

What i need to do?

Wouldn't you need something like the below in your header?
[code]
<SCRIPT TYPE="text/javascript">
<!--
function popup(mylink, windowname)
{
if (! window.focus)return true;
var href;
if (typeof(mylink) == 'string')
  href=mylink;
else
  href=mylink.href;
window.open(href, windowname, 'width=400,height=200,scrollbars=yes');
return false;
}
//-->
</SCRIPT>

[/code]
