picture-shark is an old, but still very popular tool for putting watermarks on photos, protecting them against copying, e.g. on the Internet. The application supports graphics in the most popular formats and is characterized by a banally simple operation.

It perfectly handles the processing of individual images, as well as their entire collection. It allows you to embed a watermark from a graphic file in any area of the photo, while supporting the transparency effect. picture-shark also allows you to convert photos between JPG, BMP and PNG formats.
