Graphics Piracy on the Internet
One reason the World Wide Web has become so popular is its support of graphics in Web pages. By adding all sorts of images to HTML documents, Web designers make their sites more attractive and appealing to visitors. Similarly, Internet services such as FTP and newsgroups enable users to find, download, and exchange files of all types quickly, including graphics.
This easy access to images, however, has also created a cottage industry of graphics piracy because some Internet users gather large quantities of images and distribute them online. The primary purpose of hundreds of Web sites and Usenet newsgroups is to provide users with a place to find, exchange – and sometimes even purchase – illegally obtained graphics.
The Internet provides a seemingly limitless number of pirated images, including clip art, electronic photographs, scanned artwork and photographs, video clips, and more. Although a small percentage of these online graphics are homemade (created by the person distributing them), the vast majority are illegally acquired by scanning or copying from digital sources.
The real problem is that pirates distribute these copyrighted graphics freely, ignoring the rights of the images' actual owners. The most daring pirates scan images from popular magazines, then attempt to sell them over Web sites, through newsgroups, or on CD-ROM as though this were perfectly legal.
Ignorance Is No Excuse
Many graphics pirates take up this practice because they do not understand copyright laws or the possible consequences of their actions. They believe that once an image has been digitized, it becomes public domain – that is, the property of no one and free for anyone to use. Some graphics pirates believe that by making a small change to an image (such as adding a name or logo), they are making it their personal property. However, the pirates are wrong in both cases. Photographic images, illustrations, and other types of graphics are indeed protected – in the United States, at least – by copyright laws that strictly limit the way they can be reused.
Staying Out of Trouble
Here are some steps you can take to make sure you are handling electronic graphics properly:
Consider the Source. If you find images of any kind on a Web site or newsgroup, consider them suspect. If you need electronic images for a document of your own, especially if you want to sell the document, look for sources of license-free images (you do not need to pay a license fee to use them) or be ready to pay a fee for an image from a legitimate source.
Get Proof and Permission. Regardless of where you obtain an image, the distributor should be willing and able to provide proof of ownership of the image and to grant or deny permission to use it, regardless of whether a fee is involved. If you cannot obtain this type of documentation in writing (not over e-mail or on a Web page), then do not use the image.
Never Upload Images to Newsgroups or the Web. Whether you illegally scan published images or acquire images from a legitimate source, resist the urge to put them on the Internet. Even if you own an image or have the right to use it commercially, you can assume that once it is on the Internet, it will be copied and distributed in ways you never intended.
Know What You Are Doing. If you get involved in electronic graphics, become acquainted with copyright laws and the protections in place to safeguard the rights of copyright holders.
