When one user account on my iMac takes photos with their iPhone they download to their iPhoto. I want them to be added to my iPhoto user account also and vice versa.
iMac, Mac OS X (10.6.8)
What version of iPhoto do you have? Do you want to share the same library? Or have separate libraries with the same additions?
An iPhone can only stream one "my Photo Stream", and this is bound to one iCloud account, the account that is used for the iPhone.
If you want to stream automatically from one iPhone to several persons using "My Photo Stream", all of you need to use the same Apple ID and the same iPhoto library, because My Photo Stream can only be tied to one library at a time.
With separate iPhoto libraries and IDs use shared photo streams, if your mac supports them, see:

How do I share photos in iPhoto between users on the same mac
