Display png on oled display Luma

Question

I am battling to display images on a Oled display (Sh1106 128x64). I did try with png and bpm. I can display text and graphic lines but I failing to display a picture. I have tried in many ways but no success. Here is my last attempt to display a .png monochrome 128x44. No errors but also nothing on the display.

I am using luma and PIL

I would appreciate some help.

def logo():
      img = Image.open("pathToFile/oie_2693527rQhTcSi6.png") 
      img = img.resize((128, 44))
      
      with canvas(device) as draw:
        draw.bitmap((64, 32), img)
      
      time.sleep(10)
      return
