When I use this:
<?php
$image = getRandomImage('LL/');
if (is_null($image))
{
$image = 'none.jpg';// Set to the image you wish
}
echo "<img src='$image' height=90 width=120 alt='LL'>";
?>
and pull up the Web page I look at the source and I see this:
<img src='' height=90 width=120 alt='LL'>
As you can see the 'none.jpg' default file is not coded into
the resulting HTML.
Any idea why?
Regards,
Fred
