raise exceptions.InvalidImageFormatError(

When a file is not available it would be very nice to get the information what path/file is a problem. Something like:
if self.file:
raise exceptions.InvalidImageFormatError(
"The source file does not appear to be an image".format(self.file.path))
else:
raise exceptions.InvalidImageFormatError(
"The source file does not appear to be an image")
