How can I remove the Apple Logo at the Login Screen in Mac OS X 10.7 Lion?
Also, how can I remove the brightening effect upon the wallpaper? I want to change it to my own, but the brightening effect renders it less than perfect.

appleLinen.png is also there; I forget which one. Replace them with images w/o anything in them to rid the screen of the logo.

It's a repeating image, so dimensions ought to be the same as your screen and at 72 dpi.
As to the brightening effect, as far as I know, no-one has been able to get rid of it (I personally spent a while searching the System files for something like it); so it may be drawn programmatically. Take a look at this Ask Different Question.
Or you can use Loginox to change/remove the Apple logo from Logon Screen

Do you have FileVault enabled? Because that can cause some problems when customizing the login logo. Here's a guide someone created on how to change the logo when you have FileVault 2 enabled.
