从python将图像插入MySql类型BLOB并从MySql显示到PHP

Question

I am trying to store an image from an url to my database as base64, but when I try to show it in a webpage based on php, it doesn't work..

Here's the python code:

import urllib3, io, requests
from PIL import Image
import base64

URL = 'www....com/pic.jpg'
img_conn = urllib3.connection_from_url('www....com/')
img_file = img_conn.urlopen('GET', URL)
image.seek(0)
resized_image = Image.open(image)
resized_image.thumbnail((75,75), Image.ANTIALIAS
resized_image = base64.b64encode(resized_image.tostring())

The resized_image is added to the database to a column called pic type LONGBLOB.

my PHP code looks like something like this:

$sql = "SELECT pic FROM product LIMIT 1";
$stmt = $pdo->prepare($sql);
$stmt->execute();
$row = $stmt->fetch();

$decoded_image = base64_decode($row['pic']);

$formImage = imagecreatefromstring($decoded_image);

I get the message:

PHP Warning: imagecreatefromstring(): Data is not in a recognized format in /home/...

What am I doing wrong? Is there another way to save an image from an url inside my database?
