Changes:
* Removed code that was commented out.
* BUG - NOT FIXED - Photos take a long time to import.  Figure out why it takes so long.  I think it might have something to do with making the thumbnail.
* BUG - NOT FIXED - The gallery also shows images from Google Drive and other sources.  Selecting one of those items imports the item (still takes forever) but crashes when loading the ImageViewer.
* BUG - NOT FIXED - Can only load 1 mimetype ("image/*" or "video/*").  This only allows the user to import photos OR videos but not both.
