I am in need of an app that is able to change a lockscreen wallpaper of cm 10 based roms (paranoid android 2.54 in my case) as follows:
... automatically in a changeable duration (1 week/day, hours, whatever)
... from a predefined location, folder or source (dropbox? 4chan)
... it should be able to handle too big images (zoom in randomly for example)
is there any possibility to do this?
