   Right now I use WP Post Thumbnail (plugin) and the following code to pull up images:
   <img src="<?php echo get_post_meta($post->ID, 'pft_square', true); ?>" alt="<?php the_title(); ?>" class="img" />

   I need a code which will pull up not only pft_square but pft_widescreen and pft_rectangle also. Only one image will be displayed for each post, so it needs to also recognize when no thumbnail is given if possible.

   how is it supposed to work, that the first image found of the 3 possible images is the one displayed, checking in the order you specified?

   The order doesn't matter, as long as it only displays one of the images.

   Try this code (didn't test it). It reads 1st custom field. If its empty or not existing it reads second, if 2nd empty or not existing reads 3rd.
   When a value has been stored to the variable (meaning it found a custom field) it displays the image it found. If none found no image is displayed.

   <?php
   $src = get_post_meta($post->ID, 'pft_square', true);
   if (!$src) get_post_meta($post->ID, 'pft_widescreen', true);
   if (!$src) get_post_meta($post->ID, 'pft_rectangle', true);
   if ($src) { ?>
      <img src="<?php echo $src); ?>" alt="<?php the_title(); ?>" class="img" />
   <?php } ?>

   I bet the plugin author would give you some help. Have you tried asking or dropping a comment on the plugin's page? That's a pretty nifty plugin, BTW.

   stvwlf, slight error mate in what you post...

   These 2 lines...
   

   if (!$src) get_post_meta($post->ID, 'pft_widescreen', true);
   if (!$src) get_post_meta($post->ID, 'pft_rectangle', true);

   ... i believe should be..
   

   if (!$src) $src = get_post_meta($post->ID, 'pft_widescreen', true);
   if (!$src) $src = get_post_meta($post->ID, 'pft_rectangle', true);

   Ternary equivalent... (for the sake of doing the same, another way..)
   

   <?php
   $src = (get_post_meta($post->ID, 'pft_square', true)) ? get_post_meta($post->ID, 'pft_square', true) : false;
   $src = (!$src && get_post_meta($post->ID, 'pft_widescreen', true)) ? get_post_meta($post->ID, 'pft_widescreen', true) : false;
   $src = (!$src && get_post_meta($post->ID, 'pft_rectangle', true)) ? get_post_meta($post->ID, 'pft_rectangle', true) : '/path/to/default/image.jpg';
   ?>
   <img src="<?php echo $src); ?>" alt="<?php the_title(); ?>" class="img" />
