Scrolling Images While Staying In Package

Is there any way for a client to be able to scroll through the images while they still have the package details pulled up? For example, I've got add-on options in my packages that require the client to enter an image number for their added selection. (Screenshot included) However, unless the client is currently on the exact photo they want, they would have to leave the package details (and anything they've already entered for that package), so they can scroll through the gallery again to find the image number that they want, then start all over with the package.  Is there any solution to this issue? 

You should create a collection for this. Collections are a way for customers to select multiple photos for a package. (collections and packages are the same thing).

They won't have to get photo numbers, they view the photo and add it to their collection. 

Creating Collections / Packages

To see how they work, view this photo in a gallery in the demo. Click the Collections tab and add "Simple Collection 1" to your cart. Then you will see at the bottom of the screen where to add the photos you want in the collection. 

OK, but those are for collections that already have those add-ons included in them. My package, for example, just has digital and 4x6's, but I give them the option to add wallets or magnets at a discounted rate, which aren't in the original package. I don't see a way to do that, unless I'd just need to give the option on each image they selected to add wallets/magnets of that specific image? Is that how I'd have to do it?

OK, I figured it out. :) I added the product options to the product bases, then added those product bases to the collection. So now, when someone adds an image to the package, they have a pop-up option to add those other products of that particular image.

Thank you for your help!

That's great, you're welcome.
