I've created a custom image for the login page that has some directions included for users when they first sign in. It's a simlpe "click 'Forgot your password' to get started" directive, but the image isn't autoscaling based on the screen resolution. It's fine on my wide desktop monitor, but my laptop (which most users in my environment have) has a vast majority of the huge 1400x1050 image cut off. How can I fix this so the image auto-scales based on the user's window?
