Php 通过.HTACCESS提供奇怪的热链接保护

我在wordpress上，当有人试图在他们的网站（图像）上热链接我的网站内容时，我想显示一个徽标/图像。直到这里，没有什么特别的

在网络上，我发现了一个做同样事情的网站，但是有一些不同的东西，一些奇怪的东西（我想），所以：

如果我把任何图片的链接放在我的网站上，直接放在地址栏上，我会看到我的热链接保护标志。 然而，如果我把这个网站上的任何图片的链接直接放在地址栏上，我就会看到真实的图片

我该怎么做呢？这怎么可能

在google上搜索时，我发现了很多示例，下面是我用于.htaccess的代码：

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?mywebsite.com [NC]
RewriteRule \.(jpg|jpeg|png|gif|bmp)$ https://www.dlapiper.com/~/media/Images/Insights/Publications/2015/warning.jpg [NC,R,L]

有没有办法做到这一点，就像其他网站一样

还有一件事，有没有一种方式来显示我的网站上托管的热链接的徽标？谢谢
