Replace not found image with another one via htaccess?

Question

Apache HTTP Server

How to replace an unfound image in a folder with another one using htaccess?

Answer 1

The easiest option is to place an .htaccess file in the img directory containing such code
or like this

RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^img/.*\.(jpg|jpeg|png|gif)$ /img/404.png [L]

it's already in the root of the site.

Answer 2

It's easiest like this

$("img").on("error", function(){
        $(this).attr('src', '../img/no-picture.png');
    });
