Re: Watermark script problem
Hello there,
if you use this to add the watermark
and if I understood well - you want that to happen on every image but the smiles.. then you can use this instead:
Give a try and let me know
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'
});
});

Re: Watermark script problem
@sivastar do you have a topic where you have smiles, so that I can test it live?
Re: Watermark script problem
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({
path: 'https://i.servimg.com/u/f27/14/94/21/38/icons-10.png'
});
});
