Chrome doesn't show MotionJpeg of webcam

[lichtteil]

After fixing #110 I had the issue that Google Chrome didn't show the Motion JPEG of the webcam at all. In Firefox everything worked as expected. After doing little research I found out that the MJPEG has to be wrapped in a < img >-tag so I replaced the iframe with the MJPEG as source with an image-tag. Now Chrome also shows the webcam stream.
Anything speaking against doing it like that? If not i will submit a pull request.
Cheers!
