Unable to upload images in the folder using django

I am using django 1.8 and trying to upload an image through my django blog app, however, I am not seeing the uploaded file in the folder I think I am providing the path incorrectly. Also, I have not set MEDIA_ROOT in settings.py, as I am not clear how to do that and why we need to do that. I have followed django documentation and some other useful websites to gather info on this, however unable to resolve the issue. Please help me with this.

Below is my models.py

from django.db import models
from django.contrib.auth.models import User
from django.core.files.storage import FileSystemStorage

fs = FileSystemStorage(location='E:\django\myblog\\blog\uploaded images')
# Create your models here.
class BlogPost(models.Model):
    title = models.CharField(max_length = 30)
    posted_by = models.CharField(max_length = 30)
    posted_on = models.DateTimeField(auto_now_add = True)
    description = models.CharField(max_length = 200)
    comment = models.CharField(max_length = 150) 
    tags = models.CharField(max_length=50, default = "notag")
    image = models.ImageField(upload_to = fs, default = None, null = True, blank = True)

    def __str__(self):
        #return "{0} : {1}".format(self.title, self.description)
        return self.title
