Exifer

Exifer is an image viewer that allows you to manage the metadata (EXIF/IPTC) of pictures taken by digital cameras. One of its main features is the ability to backup and restore EXIF data for all or selected images, which allows you to edit the photo with external software, and then restore the original EXIF data to the edited image. In addition, the program also enables you to insert professional watermarks into your images, that can contain dynamic information, including date, year and any available EXIF or IPTC information. Exifer can also rotate images, insert thumbnails, export EXIF/IPTC, rename, redate and run a full-screen slideshow of your images.
