How to show the uploaded image using put_image?

[HrithikShah]

here is my code.

from pywebio.input import *
from pywebio.output import *
import PIL.Image as Image
import numpy as np

def ppic():
img=file_upload("Please upload",accept="image/*")

put_image(img)

if name=='main':
ppic()

put_image() accept a bytes-like object specifying the binary content of an image.
And the return value of file_upload is a dict:

{
    'filename': file name，
    'content'：content of the file (in bytes),
    'mime_type': MIME type of the file,
    'last_modified': Last modified time (timestamp) of the file
}

So you need:

img=file_upload("Please upload",accept="image/*")
put_image(img['content'])
