My corrupted images were merely .txt files. ;-) When reading the
header libjpeg would issue an error and the io extension will throw an
exception. Now, we can argue such testing is insufficient and I would
agree but that's what we have for now. I'm gladly incorporate some
corrupted image reading into the test suite.
