ok just don't touch the data...
if you are using an image in Photoshop and you copy the image to a new image you loose your EXIF data ,But if you duplicate the Image to a new image you retain the EXIF data,,
so just don't touch the data and it will be good, short of people posting their images on Flickr and allowing others to see the Exif, the only other way for us to see the exif is if we download the image and view the exif from our computer
