How would one wait for a message with multiple photos?

[Serpentarius13]

Hello. Right now in Telegram API (as I understand), if you send multiple photos in a single message, you will receive multiple updates with :media filter. I think it happens in conversations too. What would be a correct way to wait for multiple photos, or just receive them all in a single waitFor call?

There are no messages with multiple photos (except for paid media messages which I assume you're not referring to).

Thank you for explaining it so thoroughly :) Do you maybe have in mind how to make a workaround for this? I want to make a "profile pictures" functionality for my bot. Should I use some persistent storage/sessions to accumulate photos with switch to check whether they are for this feature? I would of course be very happy with doing

await Promise.all([waitForPhoto1, waitForPhoto2...])

But the amount is dynamic and when the user doesn't load more photos, I guess conversation would come to a halt until he does?

I would personally use a conversation with a loop that pushes photos to an array until

• the maximum number of photos is received, or
• the user sends /done or clicks a button or so

I would always handle an album with 3 photos the same way I would handle three individual messages. I don't like bots that distinguish between these two types of input anyway. But this is more of a personal recommendation, you are free to build whichever bot you like :)
