Support for Image Not Found Errors

[vsc-github]

Thanks for such a light weight component. I wrap all my images in it. Since all my images are wrapped in this component, it'd be nice if I could tweak it somehow to handle Image Not Found errors(404). So if an image couldn't load, it would be handled gracefully. Any ideas how we can go about that?
