})(jQuery, window, document);

Code:
$(function() {
  $('..postbody .content img, .mod_news img, .message-text img').watermark({
    path: 'https://i.servimg.com/u/f27/14/94/21/38/icons-10.png'
  });
});

This script applying watermark including smileys...

How to remove watermark from smileys?

Hello there,

if you use this to add the watermark
Code:
$(function() {
  $('..postbody .content img, .mod_news img, .message-text img').watermark({
    path: 'https://i.servimg.com/u/f27/14/94/21/38/icons-10.png'
  });
});

and if I understood well - you want that to happen on every image but the smiles.. then you can use this instead:
Code:
$(function() {
  $('..postbody .content img:not([src*="fa/i/smiles"]), .mod_news img:not([src*="fa/i/smiles"]), .message-text img:not([src*="fa/i/smiles"])').watermark({
    path: 'https://i.servimg.com/u/f27/14/94/21/38/icons-10.png'
  });
});

Give a try and let me know Wink

Try this one instead

Code:
$(function() {
  $('..postbody .content img:not([src*="/smiles/"]), .mod_news img:not([src*="/smiles/"]), .message-text img:not([src*="/smiles/"])').watermark({
