General :: Android 4.0.3 - Where Homescreen Wallpaper Stored On ICS

As stated in the title I would like to know where exactly the default homescreen wallpaper image is stored on the ICS file system?

I am using version 4.0.3

Say for example I have a friend with a cool background wallpaper and that I want a copy of it. Where exactly would I look in the android file system on his phone to get a copy of it?

Note: I do not want to download an app which manages my wallpaper images I want to find out how it works on ICS so that I can manage it myself.

I googled a bit and found the tutorial below at the end of this email. It would appear that (on Gingerbread) wallpaper is managed by framework-res.apk

When I looked however at the different png files in "framework-res/res/drawable-hdpi" on my ICS installation I nothing what so ever that looks like my current home screen.

The wallpaper is stored under the system/media

On ICS I have 4 folders at that level
alarms
notifications
ringtones
ui

On ICS there are no images in any of these folders. The above was most likely true for Gingerbread but not ICS.

Is wallpaper managed by the launcher or by ICS itself?
