I'm using imageio for python3 that calls the pillow package which is a branch of PIL.

 frame = imageio.imread('png here')

and to make sure the frame is not being converted to something else like uint16 => uint8, I make sure of the dtype

 print (frame.dtype)

If you are trying to send the image file through FTP you might need to open the file use this

file = open(file_location,'rb')

and then you can use this to send the file 

ftp.storbinary('STOR '+file_location, file)

I use it a million times daily :)

To open images, i suggest you to use opencv or PIL module of python.
Using OpenCV:

import cv2
img = cv2.imread('here.png',0)

Using PIL:

from PIL import Image
im = Image.open("here.png")
im.show()

If you just want to open using open :

img =open('here.png','rb').read()
