Use jquery in template node (not datshboard)

Your URL is wrong.

If your settings.js file contains httpStatic: '/home/pi/JQuery/',
And you have restarted Node-red after editing it,
And that directory contains 123.png:
Then you should be able to see the image at <IP Address>:1880/123.png

I don't know if cproject.arc rather than IP address makes a difference.
