You can Setup your own route to serve static 
files. Add this method and update the static path director in the send_from_directory method and your img tag should work.

@app.route('/pic/<path:filename>')
def send_pic(filename):
    return send_from_directory('/path/to/static/files', filename)
    
For a production app however, you should setup your server to serve static files directly.
