Cant change Today image

[eenieMINI]

This is because you're setting the "Today" wallpaper instead of the touchflo wallpaper.
You need to have touchflo turned on, then slide over to your 'settings' tab (NOT Start/Settings/today) and choose "wallpaper" you can then scroll to the picture you want to change your home tab wallpaper. Be advised that unless you're running a rom with background4all setup or have set up your stock rom for background4all (search the term) you will only be changing the background when you are on teh clock screen. The other tabs stay stock (that is how the original manila work)
