how to remove "add album to cart"

After installing G2 with the matrix theme, I was able to remove "add album to cart" from the albums pages with the
help of this forum.

Made a change in modules/cart/module.inc. Change: foreach ($items as $item) {
into: foreach ($items as $item) { if (!GalleryUtilities::isA($item, 'GalleryAlbumItem')) {
and a bit below that change } to }}

Now that I have installed the modules Checkout and Checkout by e-mail I got back the "add album to cart" beneath the
album thumnails.
You can guess my question: How to remove these also I looked over and over again but I can not find where to do
Too stupid?
Further on the photothumbnails page I now have the Item Actions box with two possibilities:
Add Photo To Cart (from the cart and zip module)and
add photo to cart (from the Checkout module and Checkout module with email)
Can I show these two options to the visitors of the photopage permanently and can I change the text "Add Photo To Cart"
in something like " download in high res " Where to do ?
