When you click the Photos tab, you'll see your photo library. All the albums in your account are shown in two sections, "Your Albums" and "Friends' Albums".
At the top right, you'll see a yellow box called "Get Started." These are links to help you order prints and upload photos as quickly as possible.
To the left, you'll see a navigation bar with links to your favorites, your albums, your friends' albums, your projects and your group rooms.
The bar on the right side of the page is the photo toolbar, which contains links to all of the things you can do with your photos: ordering prints, editing photos, making cards, etc.
