Reply To: 2 questions : delete posted by / view multiple overview

Hi
I found the solution to remove the information about my first question.
You must delete code

<ul>
				<li><?php _e( 'Posted by', 'minimatica' ); ?> <?php the_author_posts_link(); ?></li>
				<li><?php _e( 'on', 'minimatica' ); ?> <time datetime="<?php the_time( 'Y-m-d' ); ?>"><?php the_time( get_option( 'date_format' ) ); ?></time></li>
				<li><?php _e( 'Filed under', 'minimatica' ); ?> <?php the_category( ', ' ); ?></li>
			</ul>
 in content-gallery.php / content-image.php / content.php

Could you help me to increase the number of previews in rows ?
