I work for one of the biggest bread manufacturers in the UK. A little while ago I was approached by our technical manager who had an idea about using a digital photo frame to display photo standards on our wrapping lines. I thought about her idea and suggested that there would be a better way to do it. I said that I would come back in a couple of days to show her what I had in mind.
My idea was to use a Raspberry Pi with a decent sized touch screen to display the images and provide an easy way to change image. I set about researching my idea and found that it would be possible to do using a bash script and FEH.
