Hi.
Sending a message to telegram. it works.
I don't know how to add an image.
Advice?
Thank you.
Did you check in the built in examples ?
No at computer, but i seem to remember that you can send a caption with a image. msg.payload.caption I think. https://raw.githubusercontent.com/windkh/node-red-contrib-telegrambot/refs/heads/master/examples/sendphoto.json
This is a simple flow example (if you would like to view the image being sent in the NR editor, please install node-red-contrib-image-tools ). The example monitors a folder and if you drop an image to it, it will be read and sent. Obviously you can feed the function node with image data directly in other ways

I think you will find msg.payload.type should be 'photo' not 'message' in the 'change' node.
You can also include a caption for the photo with...
msg.payload.caption "this is a photo of a cat"
It already works. Thank you
