function isImage()
{
return (ereg("(\.jpg$) | (\.gif$) | (\.jpeg$) | (\.png$)" .
$this->document, $trash));
}
Still working on the tutorials, this function '... is a way of telling
whether the reference ponits to an image or a webpage.'
The last part, $this->document, $trash) there is nothing about $trash in
the tutorial, or on the books site. I guess there is no way to know what
it was supposed to be for.
