With the Camera button on the item edit screen you may take a photo that will be
stored on the SD card in a directory named gbaShop. It's name will be put in the field Photo
and a label Photo will be shown in the upper right corner of the item in the lists.
You may view the photo by long-pressing the item in the list and selecting the context menu option.
This interface to the camera does not work on all Android devices and it will not always use the highest resolution.
