Image Hotlinking, its effects on Your Website, and How to Prevent

Image Hotlinking is one of the major concern for every webmaster. However, many new bloggers are not aware of this. So we will explain what is image hotlinking (also known as image theft), hot it affects your website and server, and how to prevent it?

What is Image Hotlinking?

Image Hotlinking is a way to use direct image URL from another website, and embed/use it on your own website. For example, You are posting an article with many images, and you use a direct image link from a site, and put it on your website to display. This way you don’t have to upload that image to your blog/website, and you can still use the image.

If you are new to the blogging, you might be thinking that this is good because you are getting a link from a different website. However, you should think that how such link can help you. An image link that looks like this “http://www.example.com/upload/images/example.jpg.” So this is just a link to the actual image, not the web page where that image appears.

How Image Hotlinking Affects Your Website, and Why You Should Not Allow This?

Image Hotlinking affects the performance of your website as well as Hosting Server. If a website is using direct image link from your website that means every time that image loads it will consume your hosting bandwidth.

If images from your website are used by many webmasters, it will increase the load time of your website and make your blog/website slower. This is why you must put Image Hotlinking to an end to save bandwidth and keep your website perform well.
