    You know how when you close your lid then open it so you're at the log-in screen or walk away from the laptop for a while then it goes to sleep. Then, it goes into the log in screen. It's grey/dark grey but I've seen people's log in screen with a picture there instead of the default dark grey/grey screen, how do I do that? Let me know if I'm not doing a great job at explaining this.

    I haven't tested this on Lion:

    To replace login screen background:
    1. Enter the following commands in Terminal, pressing Enter after each:
      • cd /System/Library/CoreServices
      • sudo mv DefaultDesktop.jpg DefaultDesktop_Old.jpg (enter password when prompted)
    2. Quit Terminal
    3. Rename desired image to DefaultDesktop.jpg
    4. In Finder, drag and drop the image into /System/Library/CoreServices
    5. When asked, click Authenticate and enter user name and password for your Admin-level account.
    6. Restart

    Unfortunately GGJ that doesn't work on Lion. Slightly different procedure:

    To change the background of Mission Control, you'll want to replace /System/Library/CoreServices/ You'll need to logout or execute killall Dock in the Terminal in order for this change to take effect.

    To change the background of the login window and full-screen apps that have a linen background, you'll want to replace /System/Library/Frameworks/AppKit.framework/Versions/C/Resources/NSTexturedFullScreenBackgroundColor.png.

    You may have to re-apply these changes again after installing OS X updates . Note that it changes more than just the login screen, so select the wallpaper accordingly.

    It may be cheating, but you can also set it with Onyx.

    I suspected things might have changed with Lion, so thank you for taking the time to dig out that info! I've bookmarked your post for future reference.
