I am new to Node Red. May I get help from you.
On local folder I want to place 200 Images.
Named 1.png, 2.png etc. Every 10 second, a random picture 1.png or 189.png should be shown.
OK, with the "random"-node, no problem.
I try to build my complete path to the imagefile called "1.png" with concatting the output of "random"-node and my local picture path (e.g. /home/pi/Pictures/1.png) but it does not work. For some reason, I could not build the output.
And the second problem is, how can I show that image on my dashboard? It shoud be possible, that a person, who is browsing to localhost:1880/ui/(random path)
should see my imagesin fullscreen.
Thank's in advance.
