On sale - icon in Prestashop!

Hi again I have now been posting 4 different projects, but this one is the most needed thing to be done. It is very simple. Go to my page [login to view URL] The goods "on sale" has a yellow text in the right corner. I want this to be replaced with an icon. (I have the picture). That is the only thing for now. I expect it to be done in a hurry and to a low price (under $30!) Forget the other projects I've posted. This is the one I need for now! Best regards Mads [login to view URL]
