Description

***********

The Exif module allows to display Exif metadata on image nodes. Exif is a
|
| 8 |
specification for the image file format used by digital cameras.
|
| 9 |
|
| 10 |
The metadata tags defined in the Exif standard cover a broad spectrum including [1]:
|
| 11 |
|
| 12 |
* Date and time information. Digital cameras will record the current date and
|
| 13 |
time and save this in the metadata.
|
| 14 |
* Camera settings. This includes static information such as the camera model
|
| 15 |
and make, and information that varies with each image such as orientation,
|
| 16 |
aperture, shutter speed, focal length, metering mode, and film speed
|
| 17 |
information.
|
| 18 |
* Location information, which could come from a GPS receiver connected to the
|
| 19 |
camera.
|
| 20 |
* Descriptions and copyright information.
|
| 21 |
|
| 22 |
Administrators can choose what Exif tags they want to display, and control the
|
| 23 |
order of appearance.
|
| 24 |
|
| 25 |
At this time, this module supports Exif information only with JPEG files.

Requirements
|
| 31 |
************
|
| 32 |
|
| 33 |
This module requires the PHP Exif Library (PEL), http://sourceforge.net/projects/pel
|
| 34 |
|
| 35 |
Your PHP must be compiled in with --enable-exif. Windows users must also have
|
| 36 |
the mbstring extension enabled.
|
| 37 |
|
| 38 |
PEL itself requires PHP version 5.
|
| 39 |
It does NOT work under PHP 4.
|
| 40 |
|
| 41 |
This module has been tested with PEL version 0.91.
|
| 42 |
|
| 43 |
And of course, this module also requires Drupal (version 5.0). This module won't
|
| 44 |
do anything without the Image module (http://drupal.org/project/image), as Exif
|
| 45 |
data is displayed only on image nodes.

1. Extract the 'exif' module directory, including all its subdirectories, into
|
| 52 |
your Drupal modules directory.
|
| 53 |
|
| 54 |
2. Download and extract the PEL archive into the modules/exif/pel
|
| 55 |
directory. When you're finished the directory structure should look something
|
| 56 |
