Here is what we are trying to do:

1. running Node Red on a Raspberry Pi  
2.) stored 2 pictures on the PI called, picture1.png or picture2.png  
3.) Desired action: output picture1.png or picture2.png to the hdmi output of the Pi

Here is what we have done so far and verified:  
We installed "fbi" . Then SSH into the PI and ran the command:  
pi@raspberrypi:~ $ sudo fbi -T 1 Pictures/picture2.png  
using "Liberation Mono-16", pixelsize=16.67 file=/usr/share/fonts/truetype/liberation2/LiberationMono-Regular.ttf

Result = the picture1. png displays on the hdmi output of the PI ok.

All good so far.  
We then created a "EXEC" node in Node RED and sent the same command.  
However the picture1.png does not display.  
We can clearly see on the display that the EXEC node has triggered an action , but we get error on bottom of the HDMI screen " Pictures/picture1.png" failed to load.

If anyone has any experience or suggestion, we really appreciate it.

I think you need to use absolute paths in the exec node.

i.e. /home/pi/Pictures/picture2.png

Thank you. Using absolute path works!  
Just verified.  
Hope this will other Node Red users!

Mark the reply as "solution" then its shows up in the archives as a question that was answered. I believe only the thread creator can do this.
