By default Google Chrome closes the window when the last tab has been closed. However, you can prevent it from happening using a extension which also does a lot more things.

The Chrome Toolbox extension for Google Chrome adds a ton of features to the browser. It also provides a feature to stop Chrome from closing down when you close the last tab. To enable that feature install the extension and then click on it’s icon to display then menu and click on the "Options" link.

On the options page, select the checkbox next to "Don’t close current browser window when closing last tab, create a new tab instead." This will ensure that Chrome does not close the window when you close the last tab using the Ctrl + W hotkey, you can of course close the window by clicking on "x" symbol on the browser.

- Magnify any image on a web page, set it as your wallpaper, and view it in its original size
