Helo,

I'am trying to send a picture from my Dalhua cam to telegram.  
I have look over the forum and found the solution to do that but for one kind of a reason the picture of the cam doens't go to telegram. I try to change the resulution, the size, ... nothing works.  
If i use the same picture that is stored after the snapshot, I open it with the program 'pictures' from microsoft and just save and overwrite the original file then i can send the image with the timestamp... The size of the image is alot bigger after overwriting and is still a PNG file with the same sizes . Can anyone explain me this and having a solution for that?

i use function node and node "request" module . this code will automatically send a text message (if msg.photo is NOT set) or a photo message (if msg.photo is set)..

```auto
var request = global.get('request');
const maxRetry = 2; // try 2 times
const delayBeforeRetry = 500; // 30 seconds between each retry

const token = 'XXXX:yyyyyy';

let chatId = '-000000000';
if (msg.chatId) {
    chatId = msg.chatId;
}

let payload = {};

try {
    if (msg.photo) {
        payload = 
            { url : 'https://api.telegram.org/bot' + token + '/sendPhoto',
            maxAttempts: maxRetry,   
            retryDelay: delayBeforeRetry, 
            formData: {
              chat_id : chatId, 
              photo : {
                    value: msg.photo,
                    options: {
                      filename: 'image.jpg',
                      contentType: 'image/jpeg'
                    }
                  },
              caption : msg.payload,
            },
        };
    } else {
        payload = 
            { url : 'https://api.telegram.org/bot' + token + '/sendMessage',
            maxAttempts: maxRetry,   
            retryDelay: delayBeforeRetry, 
            form: {
              chat_id : chatId, 
              text : msg.payload,
              parse_mode : 'HTML', 
              disable_web_page_preview:true,
            },
        };
    }
    
    let responseHandler = (err, httpResponse, body) => {
      if (err) {
        node.error('telegram message failed:' + err, msg);
      }
    }

    request.post(payload, responseHandler);
} catch (err) {
        node.error('telegram message failed:' + err, msg);
}

```

Is there a way that you translate it to nodes? This is a bit chinees for me...

In your original example, the issue is likely because you are **NOT** sending a buffer.

Here is a working example...

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/d/f/df4f182fabb83f588322004ad1fd4507fdfff533.png)

To make it work

- import the demo flow
- setup the BOT connection
- send `/picture` to your bot

NOTE: this demo uses [node-red-contrib-telegrambot](https://flows.nodered.org/node/node-red-contrib-telegrambot)

The demo flow...

Firstly, in order to make code more readable and importable it is important to surround your code with three backticks  
`````  
`like this`  
`````

You can edit and correct your post by clicking the pencil icon.

See this post for more details - [How to share code or flow json](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506)

As for sending image from Nas, you essentially replace the http request with whatever means you have of grabbing the image from the Nas. E.g. a `file in` node will read a file and return a buffer. Give it a go. Use a debug node to check the file in node reads a buffer of bytes.
