HI guys, another new Mac user here, so new I cann't even get past the setup

Anyway, I just bought a new Mini last week, so I have been trying to get all my pictures and favorites off my Dell into the Cloud.
Well I got the favorites, they showed up on the Mac, but I just cann't get the pictures to show up.
I have all the latest updates for both the OS and Iphoto installed, but the photo stream link just will not show up on the Iphoto page. I have been trying for days, i have Googled everything, but no luck.
Do I Need a special APP for the Iphoto ? I hope I donn't have to get the $75 Aperture one.
Any help would be appreciated, but please keep it simple

AB.
