486663 Joomla share on Facebook preview thumbnail and text fix

We have Joomla [url removed, login to view] and we need a script to fix that problem:

when sharing a document on facebook the preview is set to the first image or the text it founds and that sometimes is not the same of the article.

I've found a script for wordpress but we need something similar for Joomla.

function set_default_image(){

global $post;

$image = str_img_src($post->post_content);

if($image != ""){

echo '<link rel="image_src" href="'. $image . '" />' . "\n";



add_action('wp_head', 'set_default_image');

function str_img_src($html) {

if (strpos($html, '<img') !== false) {

$imgsrc_regex = '#<\s*img [^\>]*src\s*=\s*(["\'])(.*?)\1#im';

preg_match($imgsrc_regex, $html, $matches);



if (is_array($matches) && !empty($matches)) {

return $matches[2];

} else {

return false;


} else {

return false;
