help with image grabber

[scarhand]

alright this script works for the most part, except when you enter an URL such as news.msn.com, will not show results

 

also does not show results for some other sites

 

heres the code:

 

<?php

  if (substr($url, -1) != '/')
    $ddurl = "$url/";
  
  $ddcontent = file_get_contents($ddurl);
  
  preg_match_all("/\< *[img][^\>]*[src] *= *[\"\']{0,1}([^\"\'\ >]*)/i", $ddcontent, $ddmatches);
  
  foreach (array_unique($ddmatches[1]) as $ddimg)
  {
    if ($ddimg[0] == '/')
      $ddimg = substr($ddimg, 1);
  
    if (!preg_match("|^http://|i", $ddimg) && !preg_match("|^https://|i", $ddimg))
      $ddimg = "$ddurl$ddimg";

    $ddmysock = getimagesize($ddimg);
    $ddwidth = $ddmysock[0];
    $ddheight = $ddmysock[1];

    if ($ddwidth > 150 || $ddheight > 150)
    {
      if ($ddwidth > $hddeight)
        $ddpercentage = (150 / $ddwidth); 
      else
        $ddpercentage = (150 / $ddheight);
        
      $ddwidth = round($ddwidth * $ddpercentage); 
      $ddheight = round($ddheight * $ddpercentage); 
    }

    $ddimgtag = "<img src=\"$ddimg\" width=\"$ddwidth\" height=\"$ddheight\">";
    
    $ddext = substr($ddimg, -4);
    
    if ($ddext == '.gif' || $ddext == '.jpg' || $ddext == '.png')
      $newimages[] = array('url' => $ddimg, 'img_tag' => $ddimgtag);
  }

?>

 

any suggestions?
