- Download the file exiftags-0.98.tar.gz from the exiftags web page to your desktop. Stuffit should launch and decompress the file to a folder.
- If you haven't done so already, download and install the Apple Developer Tools. You will have to go to the Apple developer site and sign up for a free account in order to download the tools (and they're large, at over 300mb). If you purchased Panther, it should already be on one of the CDs.
- Launch /Applications -> Utilities -> Terminal
- Enter the following commands:
$ cd Desktop $ cd exiftags-0.98 $ make && sudo make install
Let's look at my picture trees.jpg's EXIF tags using exiftags:
$ exiftags trees.jpg Camera-Specific Properties: Equipment Make: OLYMPUS OPTICAL CO.,LTD Camera Model: C40Z,D40Z Camera Software: QuickTime 6.4 Maximum Lens Aperture: f/4.8 Image-Specific Properties: Image Orientation: Top, Left-Hand Image Orientation: Top, Left-Hand Horizontal Resolution: 72 dpi Vertical Resolution: 72 dpi Image Created: 2003:12:07 15:49:06 Exposure Time: 1/500 sec F-Number: f/5.6 Exposure Program: Creative ISO Speed Rating: 100 Exposure Bias: 0 EV Metering Mode: Pattern Light Source: Unknown Flash: No Flash Focal Length: 19.80 mm Color Space Information: sRGB Image Width: 2272 Image Height: 1704Now lets add a "Comment" with my copyright notice.

$ exiftags trees.jpg Camera-Specific Properties: Equipment Make: OLYMPUS OPTICAL CO.,LTD ... ... Flash: No Flash Focal Length: 19.80 mm Comment: copyright Joe Blow Color Space Information: sRGB Image Width: 2272 Image Height: 1704You can add your copyright tag to a folder full of images by doing:
$ cd /path/to/picture/directory $ exifcom -fw "copyright Joe Blow" *Those handy with AppleScript can create a folder actions script using this construct:
do shell script "exifcom -fw "copyright Joe Blow" * && exiftags *"Then attach the script to your picture folder. Now, whenever you add an image to the folder, you automagically tag it with your copyright notice! Check out this Apple tech note ... following it's lead, I came up with an AppleScript:
on adding folder items to this_folder after receiving these_items
do shell script "exifcom -fw 'copyright Joe Blow' *"
end adding folder items to
Your mileage may vary, of course, but this worked for me...
