Have a client who is making a site that will require the user to upload 40-60 pictures and I'm wondering if anyone has seen a way to integrate "dropbox" functionality into the cart. Ideally the user could just drag and drop the pictures into the cart.

What would be the best and easiest way for the customer to upload that many pictures...thinking the upload attribute will not only look unattractive but it will be a pain and slow down the checkout process too much.

any suggestions would be greatly appreciated..can't find any help ideas anywhere on the web.
