image update & replacement
I would like the database image info such as datasize, height, width & exif data to be updated when an original image is replaced with a new or better one. Right now, the only way I can see to make that happen is to remove the original, along with all of its custom field data, etc. and start all over with its replacement. It would be nice to have a single operation that would replace the original image, update its data, and update the thumbnail.
