Edit: It might help to know that I'm using python 2.7.9 (that's what was taught in my GIS class). I've almost got it working I think. Although now it's a new question. I have this code

from PIL import Image
im = Image.open("C:/users/Chrostopher/Asuna.png")

There are no error messages and my screen flashed black like it wanted to do something, but the picture didn't show/open/display. What should I do?

Thanks for all the help so far. I feel like I'm slowly (and with many mistakes) learning something useful. Old: I am very, very new at this, which is why I'm asking. I've looked around for help, but there's always one thing I don't understand and it's just turned into a very deep rabbit hole. When I've tried the code I've seen here, it doesn't work. Looking further, I need the Python Image Library (PIL). I've downloaded it, but I can't figure out how to set it up to work in Python. The file is a .gz. Is there some place I need to put the file or some way to import it? If you could answer step by step, that would be wonderful for this extreme newb.

This is the code I have (to try and open an image which is the end goal)

import Image
def main():
    filename = "desert.jpg"
    image = Image.open(filename)
    image.show
    del image

if (__name__ == "__main__"):
    main()

Is there something I'm missing or not doing right that is messing up what I'm trying to do?

    If you install 'pip', you can use this package manager to install python libraries. Your system may already have it – tom Mar 27 '15 at 19:54
  • Here is a tutorial for installing Python packages. See the pip + virtual environments part: https://packaging.python.org/en/latest/installing.html#creating-virtual-environments – Mikko Ohtamaa Mar 27 '15 at 19:56
  • You've unzipped the `.gz` file, right? That's step 1... – kindall Mar 27 '15 at 19:57

    This has nothing to do with import libraries, but image.show without paranthesis doesn't do anything ... you almost certainly want image.show() Also, you don't need to use del 99.99% of the time. Python isn't C. – Foon Mar 27 '15 at 20:07

First install Pillow with "pip"

$ pip install Pillow

Then, instead writing 

import Image

In the first line, you can use:

from PIL import Image

  • Assuming they're using Pillow and not PIL. – jedwards Mar 27 '15 at 19:55
  • I did this `code` from PIL import Image im = Image.open("C:/users/Chrostopher/Asuna.png") and it's almost working see the edited main description for the problem. Thanks for the help so far. – tictacattack Apr 03 '15 at 06:41
  • I have this `code` from PIL import Image im = Image.open("C:/users/Chrostopher/Asuna.png") end`code` When I ran the code, there were no error messages and my screen flashed black like it wanted to do something, but the picture didn't show/open/display. Any suggestions on what I'm doing wrong or need to do? – tictacattack Apr 03 '15 at 06:57
  • Maybe the image is flashing up very fast and then the program is exiting. At the beginning of the file add a new line that reads "from time import sleep". After the line with Image.open add a new line that reads "sleep(5)". This will pause your code for 5 seconds so you can see if the image really opened or not. – hft Apr 03 '15 at 07:08
  • Hm, it only flashed black the first time I ran the code (without your fixes), now it just pauses 5 seconds (which is good to know, thanks). Do I need to have something to allow it to display? I'm working in the shell btw, not an .exe if that makes a difference. – tictacattack Apr 03 '15 at 07:17
  • I added im.show() after im = Image.open(filename) and that worked. It opened in windows photo viewer (which is the default program I have set). Thanks for all the help. – tictacattack Apr 03 '15 at 07:23
