Hide Page titles with loop.php

Hi ,

I would like to remove the titles of all the pages at my site and I don’t how I will do it and what changes I must do in the loop.php .

Thank you in advance

The code that shows in the loop.php is

<?php  //Title
				if (!is_single()&&!is_page()) { ?>
				<h2><a>" title="<?php printf( $SMTheme->_( 'permalink' ), the_title_attribute( 'echo=0' ) ); ?>" class='post_ttl'><?php the_title(); ?></a></h2>
			<?php } else { ?>
				<h1><?php the_title(); ?></h1>
			<?php }
