[zerozero]

Hello Prestashoppers,

just about a few days i will start my first online webshop with prestashop.
but i have 1 question about the addyoustuff link, when you click on the image in my store he open a new window.
i would like to link the customer directly to another page in the same window.

i think it's this code onclick="window.open(this.href,'_blank');return false;
but what's code i need to link directly ??

THANK YOU!!
