Index Of Jpg Ls Mag What Does The Following RewriteRule Does?

What does the following RewriteRule does? - index of jpg ls mag

What does the htaccess RewriteRule time?
Commented, in my view.

RewriteRule. Gif $ - [L]
RewriteRule. Jpg $ - [L]
/ / Ignore. GIF y. jpg

Editor (.*)( )(/)(.*)$ RewriteRule - [L]
)(/)(.*)$ (.*)( RewriteRule admin - [L]
/ / Ignore any request with the text editor or admin

RewriteRule ^ index.php $ - [L]
RewriteRule .* / index.php
/ / Ignore any request that ends in index.php

Basically, I think all the RewriteRule statements are ignored because they are not part of the layer is only a part of the reason.

It is my perception correct?
