As it was mentioned in another thread, I uncommented these 2 lines in settings.js file
//httpAdminRoot: '/admin',
//httpStatic: '/home/node-red-static/',
Then, httpStatic: '/home/pi/.node-red/A', as i copied the folder containing images there. But still no luck. Am I doing anything wrong? I am stuck at that point.
Here's the link of thread i am following: How to enable ability to input local image files in to node red dashboard - Dashboard - Node-RED Forum
