I v made a customization on my theme, and some widget display where only title is shown without thumb.But the thing is i dont know how to remove this thumb so i v made a custom thumb size and in function added size 0,0 but i want to remove it . So the thumb get generated and in category page it could be shown but inside this widget i dont want it there as this has slowed my site. This is a part of that widget with thumb inside
<div class="widget-container">
<div class="widget-inner-list">
<h4 class="widget-header"><?php echo $title; ?></h4>
<ul class="catonlylist-links2">
<?php $recent = new WP_Query(array( 'cat' => $categories, 'showposts' => $posts_num )); while($recent->have_posts()) : $recent->the_post();?>
<li>
<?php if ( (function_exists('has_post_thumbnail')) && (has_post_thumbnail()) ) { ?>
<div class="widget-img">
<a href="<?php the_permalink(); ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_post_thumbnail('lists'); ?></a>
</div><!--widget-img-->
<?php } ?>
<div class="catonlylist-links2-text">
