If you have a website running on Apache and Linux System, you can disable hotlinks.
Hotlinking is when a website or blog use your image with a direct link, so result a consuption of your website bandwith. I assume that I’ve posted a photo of 2MB on my blog and people use it on their webpage without reuploading my photo on their host. Posted Photo was viewed 200 times in 1 hour and consume 400mb of traffic only in 1 hour!! In a day became 9.6 GB of traffic and for website that hosted this photo not is good.

First of all you have to upload one image called no_hotlink.gif on your images directory of your website. (this image is attached below)

We can use this simple authentication system only if PHP runtime is installed as Apache module.
Now we can see how it works through the source code:
