Removing the link from geodir_bubble_image

Hi there,

i managed to remove the link from the title/h4 with this code (even so i had quotation issues, but i commented it):

// REMOVE GEODIR LINK FROM TITLE beware, wrong quotations --> https://wpgeodirectory.com/support/topic/map-pop-up-2/
function my_remove_bubble_title($html, $postinfo_obj, $post_preview){
        $srcharr = array("'",'/', '-', '"', '"\"');
        $replarr = array('′', '⁄', '–', '“', '');

    if (isset($postinfo_obj->post_id)) {
        $ID = $postinfo_obj->post_id;
        $plink = get_permalink($ID);
        $title = str_replace($srcharr, $replarr, htmlentities($postinfo_obj->post_title, ENT_COMPAT, 'UTF-8'));
 $link = '<a href="'.$plink.'">'.$title.'</a>';

        $html = str_replace($link,$title,$html);
    }

return $html;
}
add_filter('geodir_custom_infowindow_html','my_remove_bubble_title',10,3);

Is there a similar code/possibilty to remove the link from the background image / geodir_bubble_image?

I found this hint as well (https://wpgeodirectory.com/support/reply/200954/), but i am not sure how to (alternatively) disable all links from the “bubble”…

Thank You in advanced for your support!
