I am preparing for a little presentation on Wifi security / dangers of public networks to a non technical audience and wanted to do a demonstration to make things a little more visual. My idea is to use a tool I had years ago which would look for network packets containing image data and would compile them as they get transmitted. And with this tool active I would ask someone in the audience to navigate to a non https website and then see the images on my PC/projector. It’s a small crowd of elderly people, so the risk of catching something inappropriate should be small. :-)

But, I can’t remember what the tool was called and my search attempts didn’t reveal anything. Anyone got an idea?

Or maybe an idea for an even better demo?

      Wireshark is my backup plan for a text based demo. Unless I am missing something pictures in Wireshark will just be binary stuff across multiple packets which won’t work for a demo. The tool I am looking for managed to identify which packets contains image data and showed them in a grid
