htaccess重定向图像以更改新域

I have Moved WordPress to a New Domain, My old domain all posts normally redirecting to new domain name but problem is images not redirecting to new domain name,

https://www.oldname.com/wp-content/uploads/2016/01/image-name.jpg

I'm using this in htaccess

RewriteEngine on
RewriteCond %{HTTP_HOST} ^www.oldname.com [NC,OR]
RewriteCond %{HTTP_HOST} ^www.oldname.com [NC]
RewriteRule ^(.*)$ https://www.newname.com/$1 [L,R=301,NC]

RewriteEngine On
RewriteCond %{HTTP_HOST} ^oldname.com [NC]
RewriteRule ^(.*)$ https://www.oldname.com/$1 [L,R=301]

Waiting your reply thank you.
