Image Guardian - the tool to protect your images
Image Guardian is an add-on to HTML Guardian for enhanced protection of the images in your web site.
HTML Guardian can protect your entire website, with one exception - it can not fully protect images. HTML Guardian can do a lot to make image theft much harder. If you choose to disable the right click in the encrypted file, visitors will not be able to right click and select 'Save image..' from the context menu (this will also disable the IE6 Image Toolbar). If you choose 'Save As' from the 'File' menu in Internet explorer, it will save the html file and all images and other files referenced in it. But if the file is encrypted, images and other files will not be saved.
However, when someone browses your site all the images included in html files are first downloaded to the local hard disk and then displayed. So all your images are somewhere on visitor's hard drive and someone can find them, although that's not so easy and most internet users don't know how to do it.
But a knowledgeable person can steal all your images.
Here comes the Image Guardian - it will split your images into pieces and will generate the appropriate code (which will be then encrypted by HTML Guardian) to display those pieces in your pages as if this is an integral, non-split image.
This will make image theft nearly impossible - if someone wants to get some of your images, he/she will not be able to get the entire image file, but only pieces of it saved under random, meaningless names. It will be very hard to determine that certain piece is a part of a certain image. Let's say your website has 10 images, and you configured Image Guardian to split them into 3 x 3=9 pieces each - this will result in 90 image pieces with random names, mixed with a lot of images from other websites visited. A determined person may still be able to find all the pieces of a certain image, but finding them and joining them together to re-create the original image will require a lot of time, knowledge and expensive image editing programs(like Photoshop or similar). In all cases this will also lead to a decreased image quality. We can say Image Guardian will decrease the risk of image theft with 95-98% (but not 100%).
Let's summarize the main benefits of Image Guardian:
Image Guardian is fully functional only in HTML Guardian Enterprise edition.
In HTML Guardian Personal and Professional editions, Image Guardian will protect images exactly the same way as the Enterprise edition, but a green 'protware.com' watermark will appear on each protected image. There will be no watermark when the Enterprise edition is used.
So testing the Image Guardian with HTML Guardian Personal and HTML Guardian Professional Edition is possible.
A complete comparison between HTML Guardian Personal, Professional and Enterprise editions you can see here.
Note that Image Guardian will not protect just any image used in your website, there are certain limitations. Please read carefully the Image Guardian section of HTML Guardian's Help file for a detailed explanation. There you'll also find information about all Image Guardian configuration settings.
