Refresh your Facebook login with your own custom design : Chrome Extension

Example :
Just goto FB Refresh and Add it to your Chrome Browser:
Little Description About App
Set your own custom background as your FB login wallpaper!
– Complete customization using the built in Theme Editor.
– Image Upload! A much requested feature that allows you to upload an image from your computer.
– Change Facebook logo to dark or light for best visibility.
– Image Size options allows you to choose a specific size for your image. You can even force the image to stretch to the browser size.
– Image Search that automatically finds images fit for your screen resolution.
– Box color option with built in color chooser to change the transparent login containers color.
– Label color options with built in color chooser to change the text color to one that matches the box color.
FB Refresh does not affect any other part of your Facebook, and NEVER has access to your personal data, passwords or anything of the like. You can enter a custom image URL as the background. This means you can add an image of any dimension, including HD wallpaper. Remember, however, that the larger the image, the slower the load time.
