WordPress自动显示图像EXIF描述信息

 

对于一些专业的摄影博客,在分享图片的时候,我们也许希望在显示图片的同时,能够在图片的旁边同时显示该图片的EXIF信息,这样对于专业的摄影人员可能会有所帮助,方便交流.我们在操作系统中或者专门的看图软件中能够很方便的看到EXIF信息,对于WordPress其实也是很容易就可以实现的.

    global $id, $post;
    if ( !isset($post_ID) || '' == $post_ID )
    return FALSE;
    $meta = wp_get_attachment_metadata($post_ID, FALSE);
    $return = '';
    if ( $meta['image_meta']['created_timestamp'] )
    $return .= date( "d-M-Y H:i:s", $meta['image_meta']['created_timestamp'] );
