Hi! I am asking users to updload a picture, for which I created a command "Foto". When they do /foto, I ask them to updload a content type "photo". However, they can upload piuctured regardless of the command; they just click on upload a picture and thatś it. How can I link the "upoload photo" to the command, so that they can only upload a picture after writing "/foto"?

[@bot.message_handler(commands=['foto'])
def send_welcome(message, chat_id):
    chat_id = message.chat.id
    send = bot.send_message(message.from_user.id, 'Subí tu foto.')
    bot.register_next_step_handler(send, photo())
    return 

@bot.message_handler(content_types=["photo"])
def photo(message):
    fileID = message.photo[-1].file_id
    logger.info("User_id, fileID", message.from_user.id, fileID)
    file_info = bot.get_file(fileID)
    #print('file.file_path =', file_info.file_path)
    downloaded_file = bot.download_file(file_info.file_path)
    with open(f"./images/{fileID}.jpg", 'wb') as new_file:
        new_file.write(downloaded_file)
    send = bot.send_message(message.from_user.id, 'Foto recibida, gracias!')]

So, you need to take a photo-input.
To do that, you have two ways:
https://github.com/eternnoir/pyTelegramBotAPI/blob/master/examples/step_example.py
second:
https://github.com/eternnoir/pyTelegramBotAPI/blob/master/examples/custom_states.py

I prefer states, because they are flexible. But choosing is up to you
