I was using It for a long time. Very Good . A rectification I have written below

In the plugin folder > see this file “get-images.js”

In the code=>
You have written ===>
/*$(‘.upload_pdf_button’).live(‘click’,function() {
// .live function become deprecated in modern jQuery library.
//I have written the rectified code,
*/
/*$(document).on(‘click’,’.upload_pdf_button’,function() {

$(‘html’).addClass(‘pdf’);

num = $(this).attr(‘data-cible’);

formfielddeux = $(‘.url_pdf_input[data-input=”‘+num+'”]’).attr(‘name’);

var id=$(“#post_ID”).val();

tb_show(”, ‘media-upload.php?post_id=’+id+’&type=file&TB_iframe=true’);

return false;

});*/
