I am putting together a new photo album and would like another Mac user to have the opportunity to add photos to the album from a remote location. Is this possible in iCould? We have not upgraded to OS X El Capitan, but can if needed.
The answer depends on what you want to do
You state a photo album - do you mean a Photo Book?
If so it is not possible to have two different Macs work on the same project (book, calendar, etc) - to work on a project you have to have the entire iPhoto library and open it
and it is not possible to have Apple print books form iPhoto in any case - PrestoPhoto can and they offer a web based book layout capability so using them your remote user could work on the book (note I have not used their services but the reports here have been generally very good)
and if you upgrade to El Captain you can have Apple print (although generally the Photos templates are different so you would want to build the book in Photos not iPhoto - and with Photos and El Captain you still can not have two people work on the same book

Are you trying to create a book in iPhoto? iPhoto Books can no longer be printed using Apple's print product service. Or are you using Photos for Mac?
It is not possible to share an iPhoto Library or a Photos library in a cloud storage. That will corrupt the library.
See Apple's support document:
If you store your Photos library in a location that's part of a cloud service (for example, Dropbox, Box, or Google Drive), your library might be damaged by the syncing process. As a result, you could lose photos.
To see your photos on all your devices, you can use iCloud Photo Library. To back up your library, you can use TimeMachine.
How do I share an iPhoto project with another remote Mac user?
