I have spent a lot of time to describe all my images with title and description. Now it was necessary to change the watermark of all my images. I have used NextGEN 2.0.7 the bulk action: "Set watermark" in "Manage Galleries" for all my galleries. After this all my descriptions are gone, on all images now is: OLYMPUS DIGITAL CAMERA!! "Set watermark" seems to run implicit "Import metadata".
Is this a bug or is this a feature, I don't know?
But if this should be a feature, please put in future versions a confirmation dialog for the user that all descriptions will be overwritten with the EXIF metadata.
