How to receive images from Telegram Bot [duplicate]

This question already has an answer here:

Can't receive images from my telegram bot, trying something like this:

import telegram
from telegram.ext import Updater
from telegram.ext import MessageHandler
from telegram.ext import Filters

def photo_handler(bot, update):
file = bot.getFile(update.message.photo.file_id)
print ("file_id: " + str(update.message.photo.file_id))
file.download('photo.jpg')

updater = Updater(token='my token')
dispatcher = updater.dispatcher
dispatcher.add_handler(MessageHandler(Filters.photo, photo_handler))

I've used this to send images generated by matplotlib. You can adapt it to your needs.

import telegram
from telegram.bot import Bot
import yachain
import cStringIO
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
import numpy as np

cfg = yachain.Config().load("telegram.cfg")

token = cfg["token"]
chat_id = cfg["chatID"]

bot = Bot(token=token)

y = [2,4,6,8,10,12,14,16,18,20]
x = np.arange(10)
fig = plt.figure()
ax = plt.subplot(111)
ax.plot(x, y, label='$y = numbers')
plt.title('Legend inside')
ax.legend()
#plt.show()

buffer = cStringIO.StringIO()
fig.savefig(buffer, format='png')

buffer.seek(0)
bot.send_photo(chat_id=chat_id,
photo=buffer)
