PC World Magazine wrote in an editorial about Visual Watermark Software:
If you upload your photos to a photo-sharing site like Flickr or even to your personal Web site, you should be aware that anyone could claim your work for their own. As PC World's Digital Focus writer, Dave Johnson, warns in a September 2008 column: "I hear stories all the time about people who post photos to online photo sites and later see one of their images gracing some stranger's blog."You can download a working demo of Visual Watermark Software at their website. They are currently offering discounts on the purchase price of the software. You can get the personal use version for $19.95 vs. the regular price of $29.95 or you can get the professional version for $39.95 discounted from $59.95. Here is an example of the type of watermark available.
Using a watermarking program like Visual Watermark is a good way to protect your photos, as Dave writes in his column. Visual Watermark lets you create your own watermarks using text or graphics, embed EXIF data into your digital files, and save your images to secured PDFs. You can perform all these tasks on batches of files at a time, as well as resize them in groups.
