PHP 5.3 - Ereg is deprecated

What steps will reproduce the problem?
1. Call the timthumb script on a php 5.3 install

What is the expected output? What do you see instead?
Should see the image and get nothing because there is error message before the 
image data in the file

What version of the product are you using? On what operating system?
PHP 5.3

Please provide any additional information below.
To fix the problem I replaced the ereg call by a preg_match. It only needs 
regexp delimiters, I choose # instead of / because of the // in http://

So simply replace the following (line 545) :
    if (preg_match('http://', $src) == true) {

        $url_info = parse_url ($src);

        $isAllowedSite = false;
        foreach ($allowedSites as $site) {
            if (preg_match($site, $url_info['host']) == true) {
                $isAllowedSite = true;
            }
        }

by

    if (preg_match('#http://#', $src) == true) {

        $url_info = parse_url ($src);

        $isAllowedSite = false;
        foreach ($allowedSites as $site) {
            if (preg_match("#".$site."#", $url_info['host']) == true) {
                $isAllowedSite = true;
            }
        }
