The example keeps around image file names only and append
them to the selected dir path, that works fine for file
scheme files, but for Android with content scheme files,
that doesn't work as good because usually the paths are
returned by a provider and managing them manually like
appending a file name to a directory (tree) path might not
work.
This patch retrieves QFileInfo objects and use the absolute
file paths to open any image.
