Picture of the Day Wallpaper

This free live wallpaper uses a bunch of different "Picture of the day" websites and shows you a different wallpaper every day.
Using the full version you have the possibility to:
- change the source website you get the images from (National Geographic, Reddit EarthPorn, Skins.be, and many more)
- choose the update interval (from 1 hour to 48 hours)
- choose if you want the image to scroll (doesn't work in newer Android versions like 4.1 due to some bad OS changes)
- choose if you want to get new images when you are on your data plan
- choose if you want to store the images on your device for good or just for buffering

Notice: this is the free edition, so some features are disabled.

This live wallpaper needs for permissions, and this is why:

ACCESS_NETWORK_STATE: to find out if you are on your dataplan or wifi (to save traffic)
INTERNET: obviously for downloading the images
WRITE_EXTERNAL_STORAGE: bufferung the images
READ_EXTERNAL_STORAGE: buffering the images
