I have many static images under a directory in my site structure, and I'm not concerned with hotlinking or copy-protecting the images. For a myriad of reasons, what I need to do is not show the image path on the site (or show a fake one). Is there any way to do this without resorting to an http handler or a worker asp.net page? You could use URL Rewritting . Doing it yourself would require you to implement a custom handler but there are third party options already available you could try. I would guess however that a simple http handler implemented as an ASHX endpoint would probably be the

This will probably get a pretty nasty response, but my server isn't the fastest at the moment, and my site loads much faster if I hotlink from the jQuery homepage so they server the content. Is this bad to do? Does jQuery eventually remove those js files from their page? Better hotlink it from Google API libraries . Very big advantages: Google is fast and highly available Separate hosts, allows the client to load JQuery simultaneously with your pages and images (browsers support only a limited number of connections per host) Probably even faster still, because many websites use it, so this

问题 What is the best/simplest way to prevent people hotlinking to images from my hosted ASP.NET website?

问题 I have a folder named - Images . This folder contains user profile pictures. Right now a user can see his image by just copying the image URL to his browser any time.

If the user directly puts the image URL, it should not be displayed. I tried to achieve this using .htaccess. This is what I have in the .htaccess file :

Prevent hotlinking image files

I want to avoid hotlinking images. Basing of this answer: stackoverflow answer I've tried to add the next snippet code into .htaccess file: RewriteEngine on RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http://(www.)?itransformer.es/.*$ [NC] RewriteRule \.(gif|jpe?g|png|wbmp)$ htttp://itransformer.es [R,L] but it is not working. When I try to access the images putting the path in the navigation bar, I can access. What am I doing wrong? You're explicitly ignoreing referers that are blank. When you type the URL in your navigation bar, there is no referer, therefore %{HTTP_REFERER
