Send images from machine A to machine B

[BartButenaers]

If you need to transfer images between multiple Node-RED instances, I would advise to send those via MQTT. You can find on this forum that others (like e.g. @krambriw) do it like that, like in this discussion:

as additional feature, there is a mqtt in node in the flow. This allows image data to be sent via mqtt. This is how I communicate images over the network from my Motion installations on several RPi's to one common analyzing computer
