How do you close all the windows on Preview?

Question

Hi, I'm running Mac OS 10.7.5 and I'm having trouble with preview. Every time I open a picture it opens in preview but there is no way to close it, I even tried the alt/options key at the bottom to no avail all it does is give me a force quit option. Can someone please help me?

OS X keyboard shortcuts
Summary
Learn about common OS X keyboard shortcuts. A keyboard shortcut is a way to invoke a function in OS X by pressing a combination of keys on your keyboard.
Products Affected
Mac OS X 10.2, Mac OS X 10.3, Mac OS X 10.4, Mac OS X 10.5, Mac OS X 10.6, OS X Lion, OS X Mountain Lion
To use a keyboard shortcut, or key combination, you press a modifier key with a character key. For example, pressing the Command key (the key that has a symbol) and the "c" key at the same time copies whatever is currently selected (text, graphics, and so forth) into the Clipboard. This is also known as the Command-C key combination (or keyboard shortcut).
A modifier key is a part of many key combinations. A modifier key alters the way other keystrokes or mouse/trackpad clicks are interpreted by OS X. Modifier keys include: Command, Shift, Option, Control, Caps Lock, and the Fn key. If your keyboard has an Fn key, you may need to use it in some of the key combinations listed below. For example, if the keyboard shortcut is Control-F2, press Fn-Control-F2.
Here are the modifier key symbols you may see in OS X menus:
(Command key) - On some Apple keyboards, this key also has an Apple () logo
(Control key)
(Option key) - "Alt" may also appear on this key
(Shift key)
(Caps Lock) - Toggles Caps Lock on or off
Fn (Function key)
Startup shortcuts
Press the key or key combination until the expected function occurs/appears (for example, hold Option during startup until Startup Manager appears, or Shift until "Safe Boot" appears). Tip: If a startup function doesn't work and you use a third-party keyboard, try again with an Apple keyboard.
