[checkout] "Add to cart" disappeared after upgrade

Before the update of the checkout module (v. 0.33 -> 0.35), the link "Add Photo to cart" was displayed under each picture in my album view.

After the update, I can see this link only in the photo view, not in the album view.

I have changed nothing in my theme.

Both album.tpl and photo.tpl use this line of code to display le linl

{g->block type="core.ItemLinks" item=$child links=$child.itemLinks}

What can I do to show "Add Photo to cart" in the album view?

Thank you for your suggestions

It works now.

That option wasn't in the previous version and was not activated by default after upgrade.

Thank you.
