Hi all !

I'm using NR 7.2.10 inside HA and I'd like to send (to Telegram) a snapshopt from my Reolink ipcamera when an event is triggered (MQTT message from BlueIris).  
I have success configuring the bot and to send Telegram text messages.

With same script as below, I have success to send a picture if 'content' is a .jpg (or something else) FILE taken from the web

```auto
if (msg.payload == "0")
{
  msg.payload = {
    chatId: 'mychatID',
    type: "photo",
    content: "https://images-na.ssl-images-amazon.com/images/I/41jaOv44rsL._SX331_BO1,204,203,200_.jpg" 
  }
  return msg;
}

```

BUT, if I chance content to image from my Reolink camera,  
`content: "http://192.168.1.5/cgi-bin/api.cgi?cmd=Snap&channel=0&rs=123daf&user=USERNAME&password=PASSWORD"`  
it does not work.

Considering that the address works perfectly in my browser but not in Telegram, I suppose it's due to the fact the link it's not a file... is it correct ?

Probably I should somehow create a picture from camera address and use it for telegram..  
How could I do this ?

Any help is really appreciated !

Try replacing all the **&** in you url with `&amp;`

```auto
content: "http://192.168.1.5/cgi-bin/api.cgi?cmd=Snap&amp;channel=0&amp;rs=123daf&amp;user=USERNAME&amp;password=PASSWORD"

```

How do you expect the telegram server to have access to your local network. The url has to be accessible from the internet.

What I do is to get the image from camera via HTTP node request. In the following node I write the image to /tmp directory and finally I build, in a Function node, the message to Telegram like this:

```auto
msg.payload = {chatId: <yourchatid>, type: 'photo', content: '/tmp/securitycam1picture.jpg'};
return msg;

```

Replace with you actual Chat Id.

There is no need to create a file, this can be all done in-memory

grab the a buffer image from camera, build the telegram msg in a function, send it...

Note: I've added a `telegram` tag to the forum as this is a commonly used service with Node-RED. I've tagged this thread and the one that Steve linked.
