wish help you to fix your issue You could try to use addslashes instead of mysql_real_escape_string before you add the image to db in addproduct and then when you query the db to do something like this:
code :
$sql = "SELECT Image FROM Product WHERE ProductId='.$product_id.'";
$result = mysqli_query($db,$sql);
while($imgarr= mysqli_fetch_array($result))
{
    echo "<img src='php/showimage.php?ProductId=".$imgarr."' />";
}

will be helpful for those in need Standard image formats consist of a header with meta data about the image and image data encoded to match the specification of that format. When you call tobytes on an array, numpy simply flattens the image data and encodes it as uncompressed bytes. The software you're using can't use this data because there's no header describing how the image is encoded. Is it compress or uncompressed? Is the image BW or color? Are the pixels encoded using RGB or HUV?
It sounds like your best option is to write your image data in a standard image format before passing it to Microsoft. You can avoid using a file by using BytesIO but the basic idea is what you already have.
code :
from io import BytesIO
import PIL

image = PIL.Image.fromarray(cropped, mode="RGB")
with BytesIO() as temp_buffer:
    image.save(temp_buffer, format='png')
    image_data = temp_buffer.getvalue()

I hope this helps . In ASP.Net, this code belongs in a separate resource (file/page) from the page where you want to show the image. Normally I use a handler (*.ashx) for this, but you can use a normal page (*.aspx) if you really want to (hint: the handler is faster and easier). Move your existing code to the ProcessRequest() method (handler) or Page_Load() method (Page), and alter the code so that instead of a memory stream it writes to the Response stream. You will also need to set the appropriate content type header.
Once that is done, update the page where you want to show the image. Use a normal
