Plugin Description
LAMEDA stands for List Attachment MEtaDAta. This function can be used as a shortcode included in the text or a template tag to display the metadata of an attachment, like EXIFs of a picture. WordPress 2.5 will extract all the EXIF data of the pictures you upload and Lameda will display them easily.
Lameda requires at least WP 2.5 (or up). It is compatible with all versions of WordPress up to the latest release (2.5.1).

1) Using shortcode [lameda]

Available attributes are:
- id: ID of the attachment whose metadata are going to be displayed. If id is not provided, the plugin will display the current post’s metadata.

image_meta : Image informations, EXIFs
width : Image's width
height : Image's height
