Closing an image opened by Pillow in Window Photo Viewer

[bigmit37]

I guess it depends on what you're trying to accomplish.  Why do you want to flash some images on the screen and immediately close them?

Since you're using the PIL already, there's ImageTk, which can display images in a Tk window: http://effbot.org/imagingbook/imagetk.htm
Or you can use something like pygame to open a few windows and blit the images, or use Tk directly, etc.

I have about 200 stock charts I want to look at, and I just need to look at them for a few seconds each. 
I want to automate this process.
