1. No right click script
The no right click script presents several problems. Many people navigate around the internet using the right mouse button. For instance, in Firefox, web pages can be opened in a new window using the right mouse button. Therefore, using this script will only end up inconveniencing many innocent site visitors who would like to make use of the right mouse button functionality.
2. Transparent overlay
This method allows you to protect an image by placing another transparent image on top of it. When someone attempts to save an image by right-clicking on it, they end up saving the transparent image instead. This method can be implemented in many different ways, including CSS, HTML, as well as other advanced programming languages. Compared to the right click script, this method is much more effective.
For the average thief, using transparent overlays can be a very effective technique. However, people who are more tech savvy can easily find where the image file is hidden in the HTML code.
3. Segmented images
What may appear to be one image might actually be two or more images pieced together. An images can be cut into pieces, and then put together again using HTML. Viewers see the image as complete. However, anyone who attempts to copy it will end up with a puzzle on their hands. The image can only be saved one piece at a time, after which the pieces then have to be reassembled to form the entire image. This is enough to discourage any would be thief.
The maid disadvantage of segmenting images is that it is very complex compared with other techniques of protecting images. It involves significant code manipulation as well as image editing. In addition, this method doesn’t work very well with smaller images.
A watermark refers to a line of text or a logo which is put on top of an image for protection purposes. It can be either translucent or solid, and is usually visible to the viewer. Most times, watermarks show the source of an image through an address or a logo. The effectiveness of this technique is determined by the location and size of the mark. A large mark which is smack in the middle of an image is very difficult to remove. However, a small mark on the side can easily be removed by cropping.
It is very easy to apply a watermark. With the proper software, you can watermark all your images within minutes. No HTML knowledge is necessary. However, watermarking your images with logos or text will only leave you with unsightly images. Since most people prefer looking at clean images, a watermark can significantly lower the value of an image, especially if the image is for sale.
The method you opt for will depend on several factors:
- The personal and financial value of the image
- The size of the file
- The type of image
- The specific role the image plays in your site
To maximize protection, you might have to use different techniques on a single image, or multiple methods on one site. However, you need to realize that there is no way of totally preventing plagiarism. All you can do is just slow down people who would want to steal our images.
