wordpress_timthumb_multisite

This function pulls timthumb into wordpress and is a easy way to load images into the script timthumb.php doesn't know how to deal with the blogs.dir directory in which WordPress stores images in Multisite, so this function tells timthumb exactly where to find those image. timthumb.php is not modified by this function, this function simply tells the script where to find the images in wordpress

download the timthumb script from http://www.binarymoon.co.uk/projects/timthumb/ then add the mr_timthumb function to your wordpress function.php

--NOTE------////////// --- This function also works on single site wordpress installs. ------///////////-----

                  'src' => $orig_uploaded_img,
                  'w'=>590,
                  'h' => 315,
                  'a'=>'top'
                  );

 mr_timthumb($timthumb_img_param);

Note: you could use : 'a'=>'top' or 'a'=>'t'
'a'=>'center' or 'a'=>'c'

To use this function you have to change the location to the timthumb script

/** $timthumblocation Stores the location of the timthumb script */

 $timthumblocation = get_template_directory_uri()."/inc/scripts/timthumb.php";

//get_template_directory_uri() looks for the script in a parent theme
//get_stylesheet_directory_uri() looks for the script in a child theme

after adding this script to the functions.php, you can use like this in a wordpress template ---to display a featured image (thumbnail) in wordpress

<?php if(has_post_thumbnail()): ?>
  <div class="photospeak-gallery-image">
   <div class="aligncenter">
      <?php
        // Featured image
        $featured_image_id = get_post_thumbnail_id ( $post->ID );
        $featured_img_post_details = get_post ( $featured_image_id );
        $featured_img_caption = $featured_img_post_details->post_excerpt;
        $orig_uploaded_img = wp_get_attachment_url ( $featured_image_id, 'full' );

        $timthumb_img_param = array (
                               'src' => $orig_uploaded_img,
                               'w' => 590,
                               'h' => 315,
                               'a' => 'top' 
                               );
                                    
 ?>

 
  <a href="<?php echo $orig_uploaded_img; ?>"title="<?php echo !empty($featured_img_caption) ? $featured_img_caption : get_the_title(); ?>" class="featured_img"><img src="<?php echo mr_timthumb($timthumb_img_param ); ?>"></a>
  
 </div>
</div>

<?php endif; ?>
