No method of image protection is wholly effective, but nevertheless, Artists should take reasonable steps to defend their images from unauthorised use. The aim of this article is to show what can be done, rather than how to do it. Free tools, software, codes, and how to advice can be easily found on the Internet, once you know what to look for.
Image preparation
The best form of protection is to make your images fit for use only as web graphics.
1. Don't make your pictures any bigger than necessary. The bigger an image, the easier it is to achieve quality prints.
2. Use image compression/optimisation software to reduce the file sizes of your images. On screen, there is little difference between a compressed and uncompressed file, however compressed files can comprise up to 90% less information, and will not withstand enlargement without severe loss of quality.
3. Watermark your images. Visible watermarking is simply a matter of placing some text, or a graphic, over your image. The trick is to achieve a balance between making your watermark difficult to remove, and not overly obscuring the image.
4. Use a correctly worded copyright notice on your web pages, and as your image watermark. This should comprise the © symbol (to let others know they should not use the artist's work without permission), the name of the copyright owner next to it (so that anyone wishing to use the image to trace the copyright holder), and the year in which the image was created (to let others know when the term of protection nulled xenforo plugins).
File protection
There are a number of easy steps that can be taken to keep your image files as inaccessible as possible.
5. Protect your image directory. Most web designers put their images and graphics in suitably named folders (sub-directories). Browsers automatically look for an "index" or "default" page within each sub-directory, and if there isn't one, they display a list of all the files in that sub-directory. This means anyone can get a complete list of all your images and grab anything they want. There isn't much point in employing other safeguards (such as no right click) if folder content lists are accessible. To stop this happening, place an index page in each folder where you have images. The page can be a blank document, or could include an appropriate message.
6. You can stop Browsers from caching the images on your web pages, by inserting the following code between the HEAD tags of your web page: META http-equiv="Pragma" content="no-cache".
7. Internet Explorer 6 has an annoying little feature called the "Image Toolbar". Whenever your mouse hovers over an image, the Image Toolbar pops up, and invites you to save, print (etc). To disable the Image Toolbar, insert the following code between the HEAD tags of your web page: META HTTP-EQUIV="imagetoolbar" CONTENT="no".
Code techniques
There are a number different ways in which you can use code to deter people from copying your website images, but unfortunately NONE of these are fool proof. They will only ever discourage the casual thief.
8. Use a rollover script to display images. When the mouse is moved over the image, a second image appears with a copyright notice, for example. Right clicking will only grab the rollover image.
