PhotoBoard is a multitouch photo browser.

Changes:

Settings menu enabled (user can change the wallpaper brightness)
Bring the pictures on top when touched (change layers order)
Allow user to add photos from a list of thumbnails / names (instead of adding them without selection)
Allow jpg and png files
Resize pictures when loading them to improve performance (max bounds are 800×800);
Keep ratio aspect (for example, if you have a square picture, it will not stretch to 4/3 ratio).
Some minor graphics improvements
