Converting the image function

We might sometimes get images in the form of base64 encoded strings if the user makes an image POST request with a suitable setting. We can create a function to handle that:

import reimport base64def stringToImage(img):    imgstr = re.search(r'base64,(.*)', str(img)).group(1)    with open('image.png', 'wb') as output:        output.write(base64.b64decode(imgstr))

We use the re module for regex to determine whether the data passed is in the form of a base64 string. The base64 module is needed to decode the string and then the file is saved as image.png.
