I have snappy set to auto snap every minute the video feed coming from my barn. I then post the image to my website. The problem is that the preview window comes up and I do not want it to. After about 3 preview pics are done, the thing hangs. I did not want to have to babysit this. IS ther any way to turn that preview thing off? I am assuming this is the reason why snappy gets confused and stops snapping.

Not sure if you can stop the preivew window, however it shouldnt matter. Try reinstalling Snappy and see if that solves your problem. BTW do you have a link to your barn cam?
