Is there just one image in the folder that starts with the 9 digit number? In that case it's dead simple (untested code):
<?php
function completeImageFilename($prefix)
{
$matches = glob('images/property_pics/'.$prefix.'*');
return $matches[0];
}
echo '<img src="'.completeImageFilename($row['MSL_No']).'" />';
?>
If you need to extract more than one image filename you should be able to modify that pretty easily.
