Installed Laravel 5 in subfolder with modified .htaccess but assets not showing - php

Question

I have installed laravel 5.4 in a subfolder, e.x. example.com/laravel.
I followed ka_lin's anwser and it seems like everything works fine except the assets as they are not showing. However, if I add "public" to the url, like example.com/laravel/public/(asset uri...) I can request the asset. I am wondering if there's anyway to work around with this.
.htaccess which resides in the project root folder:
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
RewriteEngine On
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [L,R=301]
RewriteCond %{REQUEST_URI} !(\.css|\.js|\.png|\.jpg|\.gif|robots\.txt)$ [NC]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !^/public/
RewriteRule ^(css|js|images)/(.*)$ public/$1/$2 [L,NC]
RewriteRule ^ index.php [L]
# Handle Authorization Header
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
</IfModule>

Answer 1

I finally figured out why!!
Because I named my folder to "img" instead of "images", so I have to change
RewriteRule ^(css|js|images)/(.*)$ public/$1/$2 [L,NC]
to
RewriteRule ^(css|js|img)/(.*)$ public/$1/$2 [L,NC]
And if I have any other assets like fonts, I need to add the folder name to the parentheses and modify
RewriteCond %{REQUEST_URI} !(\.css|\.js|\.png|\.jpg|\.gif|robots\.txt)$ [NC]
to include the extension.
I don't know much about apache configuration but it works for me. Hope it help other people.
