How can two users share the same data?

I just bought a new HP Windows Home Premium 64bit HP PC and am migrating over (slowly) from an older XP machine. I have set up 3 user accounts, two of them standard, and would like two of the accounts (only) to share some of the same data files. For example, I use Picasa for photo storage and I would like to share one folder with pictures between me (admin account) and my wife (standard account). The third standard account (Guest) I would like to not have access to these folders. Same with our password folder (which contains just one file).
What is the best way to set up accounts and folders to accomplish this?

I don't quite understand, Richard, as the tutorial (to me) is quite complicated. It seems to relate to sharing folders on different PCs on a network. I'm interested in sharing folders between two accounts (only) on one computer. I am a little new to all this "permissions", etc. Can you help a bit more? Thank you!

My apologies, this one is better for your purposes
Permissions - Allow or Deny Users and Groups

That tutorial was exactly what I wanted to do, and it worked! Thank you, Richard.
