Images Breaking in WordPress Multisite, Sub-directory

Hi after alot of search i am not able to find a solution to this problem. Hoping to find a solution here.
I have created a multisite on standalone wordpress after 2-3 month, By default worpdress was not allowing me to have sub-directory system but a subdomain option only.
Since i wanted to setup a sub-directory,i inserted
this code in wp-config.php

define('SUBDOMAIN_INSTALL', false);

and this my .htaccess

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

Upload Url Path, Upload Path and Uploads Use Yearmonth Folders are empty in super admin settings.
As i wanted to move the contains from main domain to subdomain, For this i used traditional xml import and later i even used Blog Copier plugin.
Every thing got imported seamlessly. but all images are breaking, which are working well in the main site.
you can check at
Main Site

When i checked the media library in sub-directory’s Dashboard, I can see all the attached images.

Please Help me and let me know where have i gone wrong.
Thank you.
