When an image fails to load there is no way to implement a custom behaviour for this. I've added a method to
IDMPhotoBrowserDelegatethat will be called when an image fails to load. The method will also pass in theUIImageViewso a custom image may be shown.I'd also like to note that
IDMZoomingScrollView'sdisplayImageFailuremethod was never called due toimageLoadingCompletenot being called unless the image succeeded. I've fixed this with my change toIDMPhoto. I can make this a separate commit, if you'd like.
