the upload function you got

now you need

-  to save the img name somewhere, 
- add a static directory (where you saved the image)
- write a function which renders the img in html with an     <img 
src="image.jpg" alt="">

its simple really. 

it fairly simple until you add javascript. to upload multiple images at 
once and need to verify the file extension and compress the images.
