When I set wallpaper from gallery, the picture file copies to specific directory. Then, I change the wallpaper again from gallery with different picture. let say, the wallpaper will be copied to /data/wallpaper when I change the wallpaper for second time, will the wallpaper replace /data/wallpaper or create the new /data/wallpaper2 and the previous wallpaper still remain? will /data/wallpaper removed when I change back to live wallpaper? note: I'm using Android 4.04 in XPERIA Tipo dual Example: http://forum.xda-developers.com/showthread.php?t=752759 Or it just for HTC Launcher??
