Lameda

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).

Documentation

1) Using shortcode [lameda]

The shortcode [lameda] can be used to display the metadata of an attachment. It has to be inserted in the text of a page as [lameda attribute1=”value1″ attribute2=”value2″].

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.
  • info: Display options for the metadata. Possible values:

    all : All available metadata are displayed. (Default value)

    name-of-metadata : Only the named metadata will be displayed. Available values (not exhaustive):

    image_meta : Image informations, EXIFs
    
    width : Image's width 
    height : Image's height 
    file : Image's full path on server 
    sizes : Various sizes of the image
    

The shortcode will be replaced by a table (with class=”dlo_lameda”) that can be styled with CSS.

Things must be done like this:

  1. Write a post.
  2. Upload a picture in the post using the button “Add a picture”.
  3. Find the id of the newly created attachment looking at the number located at the end of the class wp-image-xx (wp-image-10, for instance) given to the picture, in the HTML tab.
  4. 4) Modify the text of the post and include the shortcode [lameda] where the metadata have to be displayed. Example:
    [lameda id=10 info=”image_meta”] will display the EXIFs of the image whose attachment id is 10 in the post.

2) Using shortcode [lameda_exif]

The shortcode [lameda-exif] is meant to display metadata of an image attached to a post. EXIF and ITPC informations stored by WordPress when the image is loaded will be displayed in the chosen order. It has to be inserted in the text of a post as [lameda_exif attribute1=”value1″ attribute2=”value2″].

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.
  • info: Display options for EXIF data. Possible values:

    all : All available metadata are displayed. (Default value)

Lameda is delivered in English and French but can be easily used with other languages. You just have to create a file lameda-xx_YY.po (xx_YY being the language code of your WordPress settings. Eg: fr_FR for French) from the existing file lameda.pot using PoEdit. Then, just translate the text strings located after the “msgid” tag and put the translated string after the “msgstr” tag.

The resulting PpP-xx_YY.mo file has to stored in the “languages” directory of Lameda.
