Pligg script image crawl from other site while submitting

Here's the mod:
i tried this is in Pligg 9.9.0

1. In your submit.php file, find the function do_submit1, around line 211 (or somewhere after the code: $linkres->status='discard';
$linkres->author=$current_user->user_id;
$linkres->store(),

add

//catch images on destination url
    $pageString = @file_get_contents($url);
    preg_match_all('|<img .*?>|s', $pageString, $matches);
    //the array $matches[0] now contains the img tags, let's echo 'em:

$fulldomain = 'http://www.'. $domain;

$newimages = array();  //initialize an array as image container

foreach ($matches[0] as $path){

preg_match('/src="([^"]+)"/',$path, $b); //get the image path by $b[1], however, will need to detect relative paths and convert to absolute paths

$location = $linkres->relative2absolute($fulldomain, $b[1]);//this is to convert relative image paths to absolute image paths

$filteredimg = $linkres->filterimage($location, 120, 120);
 if ($filteredimg) {
    $image = $linkres->scaleimage($filteredimg, 100, 100); //scale bigger images and filter out images smaller than 100x100. You can modify the picture dimensions limit based on your needs.
    
    $newimages[] = array(
       'url' => $location,
       'img_tag' => $image,
        );
  }
}
 $main_smarty->assign('newimages', $newimages);
//end of get images 
In the same submit.php file, after the code line ( if(isset($_POST['link_field15'])){$linkres->link_field15 = strip_tags(trim($_POST['link_field15']), Story_Content_Tags_To_Allow);}), add the following:

PHP:

//reset link_field1 as $product_image
if(!empty($product_image_manual)){           //entered manually by user
$linkres->link_field1 = $product_image_manual;

}
else {
  if(!empty($linkres->product_image)){
  $linkres->link_field1 = $linkres->product_image;   //use link_field1 to store the image path
  }
} 

PHP:

Now, find the link.php in the /libs folder, anywhere between two function close brackets, add the following code

//Tony, get images 20080226
function relative2absolute($absolute, $relative) {
        $p = @parse_url($relative);
        if(!$p) {
            //$relative is a seriously malformed URL
            return false;
        }
        if(isset($p["scheme"])) return $relative;
 
        $parts=(parse_url($absolute));
 
        if(substr($relative,0,1)=='/') {
            $cparts = (explode("/", $relative));
            array_shift($cparts);
        } else {
            if(isset($parts['path'])){
                 $aparts=explode('/',$parts['path']);
                 array_pop($aparts);
                 $aparts=array_filter($aparts);
            } else {
                 $aparts=array();
            }
           $rparts = (explode("/", $relative));
           $cparts = array_merge($aparts, $rparts);
           foreach($cparts as $i => $part) {
                if($part == '.') {
                    unset($cparts[$i]);
                } else if($part == '..') {
                    unset($cparts[$i]);
                    unset($cparts[$i-1]);
                }
            }
        }
        $path = implode("/", $cparts);
 
        $url = '';
        if($parts['scheme']) {
            $url = "$parts[scheme]://";
        }
        if(isset($parts['user'])) {
            $url .= $parts['user'];
            if(isset($parts['pass'])) {
                $url .= ":".$parts['pass'];
            }
            $url .= "@";
        }
        if(isset($parts['host'])) {
            $url .= $parts['host']."/";
        }
        $url .= $path;
 
        return $url;
}

function filterimage($location, $minW=NULL, $minH=NULL){
 $img = @getimagesize($location);
   if ($img){                      //if image exists
    $w = $img[0];
    $h = $img[1];

        if ($w >= $minW && $h >= $minH){   //only if images greater than the minimums are they returned, otherwise, no
        return $location;
        }
        else {
        return false;                  //return no images
        }
    }
}

function scaleimage($location, $maxw=NULL, $maxh=NULL, $alt=NULL, $title=NULL){
    $img = @getimagesize($location);
    if($img){
        $w = $img[0];
        $h = $img[1];

        $dim = array('w','h');
        foreach($dim AS $val){
            $max = "max{$val}";
            if(${$val} > ${$max} && ${$max}){
                $alt = ($val == 'w') ? 'h' : 'w';
                $ratio = ${$alt} / ${$val};
                ${$val} = ${$max};
                ${$alt} = ${$val} * $ratio;
            }
        }

       return("<img src='{$location}' alt='{$alt}' width='{$w}' height='{$h}' title='{$title}'/>");

    }
}

    //enf of get images 

PHP:

You are almost done. Hang on! Next is to show the images on your template. In the submit_step2.tpl file, add the following html code to somewhere you think appropriate:

<div class="submission">

<div class="tab">
<h3>Please Choose a Product Picture:</h3>
</div>
<div class="tab-details">If none of the images below is right, you can enter one in the text field below.</div>
<div class="sub-thumbs">
<div style="overflow:auto; height:180px; width:100%;">
<table><tr>
{section name=img loop=$newimages}
<td><div class="radio-img">

<div class="wrap">
{$newimages[img].img_tag}

</div>

<input name="product_image" type="radio" id="product_image" value="{$newimages[img].url}">

</div>
</td>
{/section}
<td><div class="radio-img">

<div class="wrap">
<img src="templates/yget/images/no_thumb.gif" border="0">

</div>

<input name="product_image" type="radio" id="product_image" value="">

</div>
</td>
</tr>
</table>
You can also enter the image manually here:
<input type="text" name="product_image_manual" id="product_image_manual" size="60" />
</div>
</div>
