Photo Gallery Ecommerce

Hi.
I am use plugin “photo gallery” and whant to purchase add on “Photo Gallery Ecommerce” and I have one question, could you give to me an answer for this question:
Is it possible to download selected photos from cart directly for registered users? It means I do not want to sell these photos or send photos by emails (link) for download selected items, I just want to download them from website in convinient way everything what I want directly from website, let say by press on a button “download all”, is it possible ?
All the best, Bogdan.
