WordPress Multisite / Changed Sub-Directory / Images Broken

Hi all,

First off, here is a copy of my htaccess FWIW:

# disable directory browsing
Options All -Indexes

# Protect htaccess
<files ~ "^.*\.([Hh][Tt][Aa])">
order allow,deny
deny from all
satisfy all
</files>

<Files wp-config.php>
order allow,deny
deny from all
</Files>

# prevent viewing of a specific file
<files config.php>
 order allow,deny
 deny from all
</files>

Options +FollowSymLinks

RewriteBase /
RewriteRule ^index\.php$ - [L]
# uploaded files

I am encountering an issue where I have changed my sub-directory install site from example.com/a to example.com/b and the images are still showing a path to example.com/a, even though I am using example.com/b now. Also when I say the images are still showing, they aren’t displaying, but when viewing the source of the path, it shows that they are linked to example.com/a.

My question is, is how do I remedy this and get this sorted out appropriately? Thank you in advance for the help.
