Howto take a snapshot from DVR video streams

Hi Joachim,
You try to access with your browser an image that is stored somewhere in one of your local folders. If that should work, then everybody on this planet which would try to access /home/... would end up on your computer. So luckily for you that doesn't work.
You should put your image in a public accessible folder (which I think you have already done, when I look at your folder name?). But then you also need to access that folder on your computer via an url. That question has already been asked LOTs of times, e.g. you can look here.
Good luck with it!
