Take and display a photo with Raspberry Pi
I have been write these few lines because I lost times to understand where was the issue, and I saw many people have this, but don't solve it.
Installation OS: DietPi
I saw many informations related to modify "httpStatic" parameter in ~/node-red/settings.js. I tested with parameters httpStatic, httpAdminRoot, httpNodeRoot, ... But nothing to do !
I have been found another solution. Create a symbolic link in your "node-red-dashboard/dist" folder
- Go to ./dietpi/node-red/node_modules/node-red-dashboard/dist/
- Create a symbolic link from ./dietpi/Pictures/ to pictures (for instance) (ln -s ./dietpi/Pictures/ pictures)
- Now you could access to your pictures in: http://xxxx:1880/ui/pictures/xxxx.jpg"
- To display you can add some lines to an ui_template (see in the flow)
You will find below a complete flow which running.
