Hi Sassa,
I didn’t want the thumbnail on the portfolio page displayed at the top of my pages either. So here’s what I did, maybe it will help you, or maybe someone else can guide us both.
Open up the theme editor: Appearance -> Editor
Select the file: single-portfolio.php
Backup the text for this file, in case you flub something.
Remove the following code:
< ?php
$thumb = get_image_path(get_post_meta($post->ID, 'boldyp_pitemlurl', true));
if (!$thumb == '')
{ ?>
<div class=”portfolioimg”>
<img src=”< ?php echo get_template_directory_uri(); ?>/timthumb.php?src=< ?php echo get_image_path(get_post_meta($post->ID, 'boldyp_pitemlurl', true)); ?>&w=960&zc=1″ alt=”< ?php the_title(); ?>“/>
</div>
< ?php }?>
That should stop injecting the image at the top of the page, for any pages that are using the Portfolio template.
