If you choose not to watermark, you'll want to delete this section:

""" Apply a watermark to an image """
mark = Image.open(watermark_img)
im = Image.open(image)
if im.mode != 'RGBA':
im = im.convert('RGBA')
layer = Image.new('RGBA', im.size, (0,0,0,0))
position = (im.size[0] - mark.size[0], im.size[1] - mark.size[1])
layer.paste(mark, position)
outfile = join(out, basename(image))
Image.composite(layer, im, layer).save(outfile)
return outfile
The script continues by uploading the image, creating the QR code and the web page,
and offering a shortened URL:
