How to redirect all pictures to a folder?

Question

Nginx

Good day.
Tell me how to redirect all the pictures to a folder, given that they were all in the root of the site.
Example site.com/img.jpg -> site.com/images/img.jpg ; site.com/img.gif-> site.com/images/img.gif
This solution for some reason gives a looped redirect:

RewriteEngine On
RewriteRule ^(.*?)\.(jpg|jpeg|png|gif)$ "/wp-content/uploads/2020/01/$1.$2" [R=301,L]

Need help for both htaccess and nginx

Answer 1

RewriteRule ^([^/]+\.(jpe?g|png|gif))$ /wp-content/uploads/2020/01/$1 [R=301,L]

Rewrite ^/([^/]+\.(jpe?g|png|gif))$ /wp-content/uploads/2020/01/$1 permanent;
