I changed a bit the behaviour of your mod, because of my EXIF problem. Now, it works like this :
- you post your picture, wallpaper sized.
- pixelpost resizes the picture at the display size
- You have now two versions of the picture : wallpaper and "normal" display.
- If there is no EXIF information inside the normal display picture, it will read the information inside the wallpaper picture.
Let me know if you are interested by the mod.
