Tidy removing img and link paths

[Karl Groves]

I created a quick function I can call to clean up stuff input into forms
with tidy. The problem I'm having at the moment is that everything within
the 'src' attribute of <imgand within the 'href' attribute of <ais
being stripped to only "/". So, for example: "<img
src="/images/foo.gif">" is being changed to "<img src="/">"

Any idea what's causing this?

Here's the function. Nothing special, really.
function tidystring($string){
/* here we're going to use Tidy for the additiontal cleanup */
$config = array(
"bare" =true,
"clean" =true,
"doctype" ="omit",
"logical-emphasis" =true,
"quote-ampersand" =true,
"quote-marks" =true,
"quote-nbsp" =true,
"show-body-only" =true,
"word-2000" =true,
"drop-proprietary-attributes" =true,
"drop-font-tags" =true,
"drop-empty-paras" =true,
"hide-comments" =true,
"join-classes" =true,
"join-styles" =true
);

$tidy = new tidy;
$tidy->parseString($string, $config, 'utf8');
$tidy->cleanRepair();
return $tidy;
}
