Mr.NEM

How is it wrong code? I copy pasted his code and it’s working as intended.
The image title is correctly displayed beneath images.

Sure thing, but i’m still a newbie in term of wordpress functions, so i don’t know what could cause the query string to be modified within that code :

<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
	<?php if ( has_post_thumbnail() ) : // check to see if our post has a thumbnail	?>
	<div class="row-fluid">
		<div class="post-thumbnail span12" style="margin-bottom:40px;"><?php the_post_thumbnail( ); ?></div>
	</div>
	<?php endif; ?>
		<header class="entry-header">
			<h1 class="entry-title"><?php the_title(); ?></h1>
		</header>

		<div class="entry-content">
			<?php the_content(); ?>

		</div><!-- .entry-content -->
		<footer class="entry-meta">
			<?php wp_link_pages( array( 'before' => '<span><span class="page-links">' . __( 'Pages: </span>', 'mytheme' ), 'after' => '</span><br />' ) ); ?>
		</footer><!-- .entry-meta -->
	</article><!-- #post -->

Thanks a lot man, it worked !
