Does anyone know if there is a plugin available for the GIMP that will let you view and edit all the EXIF information associated with an image?
To be honest I'd probably use some photo management software for managing the exif data. It's likely to be more powerful and allow for various batch operations. If you're on Linux, you could try one of the ones listed under this question.
But if you insist, you could try
Don't know if that's enough for you, but as I say, I'd use something else for exif manipulation.
