FWIW; I vote for the jpeg package.

For the interested; a summary:
 jhead is a Exif 2.x information extractor/manipulator.

To date I have yet to find any easier to use exif-utility.


 Exif-information is available in a majority of the JPG-images that gets
created with almost any current digital still image camera.

 Running jhead on such an image might look like this:

$ jhead 2004-06-06_11.53.16_z-4002.jpg
File name    : 2004-06-06_11.53.16_z-4002.jpg
File size    : 1277295 bytes
File date    : 2004:06:06 11:53:16
Camera make  : Minolta Co., Ltd.
Camera model : DiMAGE Z1
Date/Time    : 2004:06:06 11:53:16

Flash used   : No
Focal length : 12.1mm
Exposure time: 0.0012 s  (1/800)
Aperture     : f/3.2

The jhead sources - and an url:

$ ls -l
total xx
-rw-r--r--    1 Hannu          92 May 31 10:55 from.url
-rw-r--r--    1 Hannu       43680 May 31 10:56 jhead-2.1.tar.gz

$ cat from.url
[InternetShortcut]
URL=http://www.sentex.net/~mwandel/jhead/
Modified=600A9E11ED46C40111


To compile it under cygwin use the magic keywords:

$ tar -zxvf jhead-2.1.tar.gz && \
  cd jhead-2.1 && \
  make && \
  ./jhead -h

or some such...
 given that you have gcc, gcc-c and make (more?) installed ;-)
