 const Image* img = DxImage.GetImages();

Windows Store apps have limited access to file locations.

See File access and permissions in Windows Store apps on MSDN.

You generally can only write new files to :

auto folder = Windows::Storage::ApplicationData::Current->LocalFolder;
// use folder->Path->Data() as the path base

Note that there are some details on the DirectXTex and DirectXTK documentation wikis for these issues. You may also find the discussion forums on the CodePlex a better place to ask specific questions about DircectXTex or DirectXTK.
