Exifography (formerly Thesography) displays EXIF data for images uploaded with WordPress. It utilises WordPress’ own feature of storing EXIF fields in the database, and also enables import of latitude and longitude, and flash fired EXIF to the database upon image upload.
The purpose of this plugin is to make dislaying EXIF data as convenient as possible, while using as much of WordPress’ native image handling as possible.
EXIF can be displayed via a shortcode, via a function in your theme files and it can be inserted automatically for the first image attached to a post.
Features include: 
* Location shown as coordinates or static Google map, and linked to Google maps (or not) 
* Customisable HTML layout via plugin options 
* All output can be manipulated via a filter 
* Language localisation
