Modify "add to cart" "write a review" "tell a friend"

[haredo]

How can I modify the images of "add to cart" "write a review" "tell a friend about us":

I know I have to create images that will replace the former ones. I can do that. But from where can I change/replace this pictures?

Thanks,
Marlake

includes/ templates/ templates_default/ buttons/ english

1. remember the override directory
2. includes/ templates/ your_template/ buttons/ english
3. this is where you will upload your new buttons.
4. This is a site I use for buttons for the whole site.
5. http://zen-bck.mediakitchen.de
6. But, this is a global change or only select the buttons you wish to change when saved in a file for upgraded button for web site..
