    Display only images in News List...

    I am using Concrete5 on a site I'm working on. Below is the News List display view.php file needed in the block to display the content from news pages. The code allows images entered in the WSYIWYG to appear in the RSS list. I want to know how I can edit the code below, so it shows only the these images from the $content not the text. Can anybody help me on this? Thanks

    PHP Code:
    <?php     
    defined
    ('C5_EXECUTE') or die("Access Denied.");
        
    $html Loader::helper('html');
        
    $uh Loader::helper('concrete/urls');
        
    $bt BlockType::getByHandle('news_list');
        global 
    $c;


       
    $rss_address $controller->getRssUrl().'?ctID='.$ctID.'&bID='.$bID ;

        if (isset(
    $_GET['pageno'])) {
           
    $pageno $_GET['pageno'];
        } else {
           
    $pageno 1;
        } 
    // if
        
    ?>
        
        <div class="newsflash">
        <div class="headtitle">
            <h1><?php echo $rssTitle ?></h1>
            </div>    
        <?php    



        
    if (!function_exists('newslistParse')) {
        
            function 
    newslistParse($url,$thumbnail,$thumbwidth,$time,$content,$title,$date){

    I'm afraid I don't know anything about this system, but if I understand what you want, you want the newslistParse function to exclude the text in what it shows. There are two calls to this:
    PHP Code:
    newslistParse($url,$thumbnail,$thumbwidth,$time,$content,$title,$date
    Replace $content with '' or null and that should prevent the $content value from showing in the output. Note that it will still include the div, but you can technically rewrite the function or remove it (not recommended as there may be other places calling this). I'd leave it and if absolutely necessary add a class control of some sorts to hide the div if its empty.
    PHP Code:
    header('HTTP/1.1 420 Enhance Your Calm');

    I don't want to hide the $content completely, because the images I need to show are part of the $content.

    How can I display just images from $content? Thanks

    OK, I have got the images to appear using the following code:

    PHP Code:
    <div class="description">
    <?php {preg_match_all('/<img[^>]+>/i',$content,$images);} print_r($images); ?></div>
    However, the Array info is appearing between the images, like this: Array ( [0] => Array ( [0] => 07-Green.gif [1] => 05-Red.gif [2] => 21-Yellow.gif [3] => 20-Blue.gif ) )

    How can I edit the code so that only the images appear, without the array details? Thanks

    This has solved my problem.

    PHP Code:
    <div class="description">
    <?php preg_match_all('/<img[^>]+>/i',$content,$images); ?> <?php foreach($images[0] as $img){ echo $img;}?></div>
