Image Hot Linking and Bandwidth Theft - Now Disabled

Post by azpyroguy » Wed Jun 27, 2007 9:31 am

What is hotlinking and bandwidth theft?

Bandwidth theft or "hotlinking" is direct linking to a web site's files (images, video, etc.). An example would be using an <img> tag to display a JPEG image you found on someone else's web page so it will appear on your own site, eBay auction listing, weblog, forum message post, myspace, facebook, etc.

Bandwidth refers to the amount of data transferred from a web site to a user's computer. When you view a web page, you are using that site's bandwidth to display the files. Since web hosts charge based on the amount of data transferred, bandwidth is an issue. If a site is over its monthly bandwidth, it's billed for the extra data or taken offline

(essentially costing them more money to have the site up and running)

A simple analogy for bandwidth theft: Imagine a random stranger plugging into your electrical outlets, using your electricity without your consent, and you paying for it.

How Do I know I am hotlinking?

This is how you might display an image graphic file in the HTML on your own web page, and images that you are hosting yourself:

<img src="image.jpg" height="350" width="200">

This tag tells the site to request the file image.jpg on the same server as the rest of the files on the site. If you were to hotlink an image from an outside server, the HTML might look like this:

<img src="http://notmysite.com/image.jpg" height="350" width="200">

This tag tells the site to request the image.jpg from a different server other than your own. Every time the page is loaded, the outside server has to use its bandwidth to display the image. To avoid this problem, don't link to files on servers that don't belong to you. To share images and files on your own web page, upload them to your own server's directory or to a free image hosting service that allows direct linking.

Why should I stop hotlinking?

Hotlinking can have a lot of undesirable consequences. One is the so-called "switcheroo". If you've linked to an image on someone's server, what's to prevent them from changing the image you linked to? This can have humorous results. Since most sites, forums, etc. have strict policies about offensive images, it wouldn't take much for an aggravated webmaster you've been stealing bandwidth from to shut you down completely with an unwanted "switcheroo".

Displaying an image or file that doesn't belong to could be a violation of copyright, making you open to litigation. The owner of the file could utilize DMCA law to have your site shut down and your information given for use in legal proceedings.

Now, we have placed some exclusions on this... so some hot linking is allowed.

1. You can still post images in your BBS posting, and link to them in the photo gallery.

2. Our affiliated websites can still hotlink to us (because we host them, or the are search engines.)
a. asasand.org
b. asasand.com
c. glamisonline.org
d. isdratrt.org
e. google.com
f. yahoo.com
g. glamisdunes.com
h. or any 'cached' image from a search engine.

Images that are affected are: gif, jpg, jpeg, png, and bmp.

Your probably asking now... what will happen if I hot link to a image and my site is not listed as being able to do so... visit this page to see what will now show up on your browser.... instead of the image you had expected to show up, click here.

If you think your site should be listed as being able to link directly to images hosted by us, please submit your request on the contact us page on the main website, and we can discuss your needs.

It is my view that if a website doesn't want anyone to hotlink images from their sites, they should set it up to not allow it to be done. I know some websites do that. We (this BBS) should not be policing bandwidth usage of other peoples/orgs site for them. We should keep our nose in our own business, not theirs.

Actually the way it works... we have to block it from our end, and the only way to do such a thing is to implement said configuration to prevent it from happening.

I have researched this topic alot, and found this was the easiest way of obtaining a goal, and limiting the load on our server.
