If you post your pictures on the Web, odds are that you are already well aware of the challenges in protecting them. Without some measure of protection, anyone who visits your site can simply right click the image, do a “save as” and post it to their site.
Worse yet, many will not bother to save the image and, instead, will just copy the URL and paste it to their site. This not only plagiarizes your image, but robs you of your bandwidth and money.
But what is most frightening is that, unlike text plagiarism, image theft is not easily detected by search engines. As of right now, there is no free, easy and effective way to search for duplicates of your image should you want to check for plagiarism.
Given the amount of time and effort that can go into an image it is more important than ever to take precautions to ensure that the work does not get misused.
