Sharing info between accounts?

Hello, Mac noob here. Just made the switch.

I set up 4 accounts on our iMac, one for each member of our family. My wife and I each have administrator capabilities, while the kids are users.

I loaded all of our digital photos into iPhoto under my account. My kids would like some of those pictures in iPhoto under their accounts.

When I log in to their accounts and use Spotlight, I can't find the pictures on our computer. Do I need to load the pictures under each account individually? I'm trying to avoid that.

Thanks!
