I don't understand why this would make any difference. The code above is to
send the actual image data, the resizing is done when you create the
IMG-tag, which I assume you create somewhere else. Or don't you have an
IMG-tag at all, just a link?

If you actually want to resize the image itself to send less image-data, the
PIL library can be used to do that. But it seems easier to resize the image
before putting it into the database in that case.
