+EXIF Info
+==================
+
+* Retrieve EXIF informations from pictures
+
+##How to Use
+
+1. Install the PIL (Python Imaging Library) libraries, please refer to http://pythonware.com/products/pil/ or your OS manual for instructions.
+2. This plugin is an extension to the Gallery plugin, so first install it, and refer to its README for usage instructions.
+3. Add 'exif_info' to the plugin list.
+
+If you want, you can also specify in your configuration: 
+
+	EXIF_INFO_DEFAULT = True/False
+
+To set whether or not to retrieve by default the EXIF informations from your pictures. This setting can be overriden on a per article/album basis.
+
+###Articles
+
+Override on a per article/post basis the default behaviour by adding the following:
+
+	exifinfo: "True"
+
+or
+
+	exifinfo: "False"
+
+###Gallery Page
+
+At this time the Gallery page is *not* supported.
+
+##Examples
+
+###article.html
+
+    {% if article.album %}
+        {% for image in article.galleryimages %}
+             {% if article.galleryexif and article.galleryexif.get(image) %}
+                <table>
+                    {% if article.galleryexif.get(image).get("Model") %}
+                    <tr><th colspan="4">{{article.galleryexif.get(image).get("Model")}}</th></tr>
+                    {% endif %}
+                    {% if article.galleryexif.get(image).get("LensModel") %}
+                    <tr><th colspan="4">{{article.galleryexif.get(image).get("LensModel")}}</th></tr>
+                    {% endif %}
+                    <tr>
+                    {% if article.galleryexif.get(image).get("ISOSpeedRatings") %}
+                        <td>{{article.galleryexif.get(image).get("ISOSpeedRatings")}}</td>
+                    {% endif %}
+                    {% if article.galleryexif.get(image).get("FocalLength") %}
+                        <td>{{article.galleryexif.get(image).get("FocalLength")}}mm</td>
+                    {% endif %}
+                    {% if article.galleryexif.get(image).get("FNumber") %}
+                        <td>f/{{article.galleryexif.get(image).get("FNumber")}}</td>
+                    {% endif %}
+                    {% if article.galleryexif.get(image).get("ExposureTime") %}
+                        <td>{{article.galleryexif.get(image).get("ExposureTime")}}</td>
+                    {% endif %}
+                    </tr>
+                </table>
+            {% endif %}
+        {% endfor %}
+    {% endif %}
+
+##Reasoning
+
+This was developped as an external plugin, instead of adapting the Gallery plugin because this relies on the PIL libraries to be installed, and working.
+
+As this set of library may - or not - be available on a given platform, it seemed unreasonable to limit the Gallery plugin to the systems where it is.
