How do you change the logon screen in 10.7.4

Question

A few months ago I changed my logon screen background to something more desirable for my tastes. Recently, I updated my software to vers. 10.7.4 and the update reverted my custom logon screen back to the original. I tried changing it back, but it seems as though the location of the image has been changed as when I navigated there, my original "Custom image" was still there, but my actual logon screen still displays the factory image. What gives? Where do I go to change back to my custom image?

I love Apple and I love my MBP. Also, I understand where your coming from when you say I shouldn't be messing around with the OS resources. Normally, a person would not go through the trouble (and/or the possible catastrophic consequences) of changing things like this, but computers fascinate me and I love learning about them. I'm sure there are many others out there like me. It is just a personal preference of mine to want to change the logon background (and gain the learning experience that goes along with it). My preferred logon screen DOES pay homage to Apple and being a second year programming major (yes, I am thus far only in my second year) it is what I like to learn about. I would not have endeavored in something like this if I did not think I could fix it if something went wrong. Like I said before, it would be nice to be able to change it as easy as it is to change the desktop background, but the learning experience is valuable too.
