Loop displaying featured image problem

Howdy all.

I have this loop

<?php

                                    global $post;

                                    global $data;

                                    $args=array('post_type'=> 'logo','post_status'=> 'publish', 'orderby'=> 'menu_order', 'posts_per_page'=>6); 

                                    $logo_posts = query_posts($args);  

                                    //print_r($postsss);

                                    $i =1;	

                                    while ( have_posts()):the_post();

                                        $class = "";

                                        if($i == 6): $class="last"; else : $class=""; endif;

                            ?>

                            <?php
							  $feat_image = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
							?>

                            <div class="logo span6 <?php echo $class;?>"><!--Logo start-->

                                <img src="<?php echo aq_resize($feat_image, 157, 95, true ) ; ?>" alt="<?php the_title(); ?>" />

                            </div><!--Logo end-->

                            <?php endwhile;?>	<!--End the loop-->		

                            <?php  wp_reset_query(); wp_reset_postdata();?><!--reset post data-->

My problem is the loop is displaying only the first image, the third image and so on. The second and the fourth image are not displayed. Here is a preview for a better understanding https://tinypic.com/view.php?pic=o2weq&s=5
