I was looking at a way for my change of wallpaper to stick after the screen is turned off and back on and it seems I found a way. This requires root. It's pretty simple you just have to:
Not anywhere near ideal but it works for the time being. Much easier than injecting images into an app.
Code:
1. Change wallpaper within a launcher like ADW.
2. chmod 550 /data/data/com.android.settings/files/wallpaper
If you want to change it again you have to chmod it back to something like 755 and then back to 550 once you've changed it back to write-protected again. You can freely change between live wallpapers for some reason once it's 550
