Hi, I’m trying to send multiple pictures to my telegram bot, then n8n ai bot need to analyze it.
When i use the build in n8n chat, the chat will pass all images to the ai bot, and my automation works 100%.

But i want to use my telegram bot instead of the n8n chat function. When i send multiple images to my telegram bot, it will only pass 1 image instead of all images.

I found a post of @shuui and he made it work, but the post is a little to complicated for me.
I need to do something with media_group_id.. Dynamically send variable groups of media on Telegram with n8n - #2 by shuui

Hope someone can help me.

So what happens is, if you send 2 photos using telegram, you’ll get the workflow executing 2 times, one per image. I would maybe recommend you first detect whether an image was sent, store the images to disk or a cloud bucket, then in a separate execution or a followup message, instruct your bot to pull the stored images and use them. You can use the media_group_id as a unique identifier to link the images together. I assume you need all images to be passed to the llm agent at the same time?

@Eyas I chatted with Chatgtp, gemini, Claude for hours, but did not managed to get it done.

Wouter, I swapped from telegram to a (custom) discord node, and managed to get it done. It took me so long, first i will use this discord method, but i will try telegram again, when i have some spare time.

The only other option is to maybe use a custom api call using http requests like the link you shared. Im not 100% sure if this is how telegram works, or if this is how the telegram node in n8n works.
