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 many known formats including jpg, gif, bmp, tiff and png and save the image in the same 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 could 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.

Many normal users who visit your website will probably dislike that all images on your website have a copyright notice thus preventing the full view of the image. It is up to you to decide whether to use it to fight content theft.
