Limit Number Of Images In Buy All Digital Download

How can I setup a "Buy All Digital Download" so that one person can't select all the images for an entire team.

I'm thinking maybe an option where they select 5 images for immediate download at $xxx and then send them a dropbox link with the rest of their child's images.

You could do it that way.

Another option is to add the buy all to the price list and edit the product group the buy all is in and check the " If this product group includes Buy Alls, ONLY offer when a customer is ordering from favorites."

And instruct your customers to add their photos to their favorites, then view and buy all from there.
