Create visible copyright notices for images
CopyRightLeft is a Open-Source application that has two processing modes. The first is an image by image mode that manipulates one image at a time. You can use the tool to open an image in popular formats such as jpg, gif, bmp, tiff and png and save processed images in all supported formats except gif. You can then enter a text, define the font size, color and many other options. It is for instance possible to add the copyright notice at the bottom of the image, in the center or rotate it to place it diagonal.
Instead of opening and manipulating every image by itself you can use batch processing to process a number of images at once. It is possible to select a number of files, a directory or a file list from a text document and process them one after the other. CopyRightLeft can be run in most Windows versions. I was able to run it in Windows Vista Home Premium and Windows XP without problems.
Uusers who visit your website will probably dislike that all images on your website have a copyright notice as it makes the image look inferior to its clean original state. It is up to you to decide whether to use it to fight content theft.
Copyrightleft is a useful program that is absolutely easy to use. Probably the best option to use it in my opinion is to add the copyright notice to the bottom of the image where it usually is not as distracting as directly in the middle or other locations of it.
Update: The application is compatible with all recent Windows systems including Windows 7 and Windows 8.Advertisement
At the moment picture-shark (imho) has more functionality and become more flexible.
I was using the ‘Add text’ option in XnView to do this but it was a pain if I had a lot of images. This software looks promising.
You can batch edit by recording actions in Photoshop (at least in CS). Watermarks can be done with this method.
