Exif Data

[motty07]

Hi

I'm trying to display EXIF data for a photo on an attachment page.

I've established the following by using the tool at http://www.wisegeek.com/how-can-i-vi...photograph.htm to examine the image files that wordpress has uploaded into its image folder.

Results are:

1. The original full size image has the EXIF data intact.
2. All the smaller images that wordpress creates (and therefore the ones it uses in attachments have the EXIF data stripped)

I suspected that the EXIF data would be stripped for the compressed images. However, according to this page http://www.bloggingtips.com/2008/07/...lery-and-exif/ and others the EXIF data is stored in a table for use.

When you upload your photos the EXIF data is stored in the post meta data table.

However, searching all the wordpress database (using php admin to search all tables) for terms such as Nikon etc. (my camera) reveals that no EXIF data is being stored anywhere in the database?

Is Genesis doing this?

My function displays nothing on attachment page:

PHP Code:

add_action( 'genesis_after_post', 'dbm_exif' );
function dbm_exif() {
    if( is_attachment() )
    $imgmeta = wp_get_attachment_metadata( $id );
    echo $imgmeta['image_meta']['iso'];
    echo $imgmeta['image_meta']['camera'];
    echo "hello";

} 


Others seem to have the same problem and its not been resolved e.g.

Can anybody throw any light on this?

Thanks in advance


UPDATE

Ok. I've done a bit of digging around and think I have found the cause of the problem.

This post helped me http://wordpress.org/support/topic/image-meta-data

At the bottom the guy says:

i was missin php module EXIF.

marking it as solved

It led me to think that as I was working on a local server (WAMP) it might not have had this php module EXIF installed (whatever that is!!!).

Tried it on a live site and the EXIF data does get stored in the database and my function now works.

Presume this missing php module EXIF (from WAMP) is the cause?
