first image in post problem

  • hello guys, i want todisplay in index only the firdt image in post, i`ve tried a lots of plugins and hacks but nothing seems to get the job like i want until i found this
    // Retrieve the src of first image in a post
    function bm_extract_string($start, $end, $original) {
    $original = stristr($original, $start);
    $trimmed = stristr($original, $end);
    return substr($original, strlen($start), -strlen($trimmed));
    function getFirstImage() {
    $content = get_the_content();
    $pic_string = bm_extract_string(‘src=”‘,'” ‘,$content);
    $imagesize = getimagesize($pic_string);
    list($width, $height, $type, $attr) = getimagesize($pic_string);
    $link = get_permalink();
    $title = get_the_title($post->post_title);
    echo ‘‘;

    <?php getFirstImage(); ?>

    it works fine, i even modified a little bit to resize my images

    $width = '225';
    $height = '140';
    echo '<a href="'.$link.'" style="background:url('.$pic_string.'); display:block; width:'.$width.'px; height:'.$height.'px;" title="'.$title.'"></a>';

    now for the hard part, i want to change the permalink, so when you click on the image to show u the full image … i`ve tried get_image_url(), not working, so … any ideas ??
