Yasmin Theme – Display Portfolio Projects in Homepage Slide

Does anyone have advice for how to display portfolio items instead of news items in the main page image slider for the Yasmin theme? Obviously, I am not a coder.

Here is how the theme queries portfolio pages:

<?php 	$query = new WP_Query( array( 'post_type' => 'portfolio','posts_per_page' =>'3' ) );
	           	if ($query->have_posts()) : while ($query->have_posts()) : $query->the_post();	?>

Here is how the theme queries slider images:

<?php 	$count = of_get_option('w2f_slide_number');
				$slidecat = of_get_option('w2f_slide_categories');
				$query = new WP_Query( array( 'cat' => $slidecat,'posts_per_page' =>$count ) );
	           	if ($query->have_posts()) : while ($query->have_posts()) : $query->the_post();	?>

		<li>
				<?php $image_attr = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID), 'top_feature'); ?>
				<a href="<?php the_permalink() ?>">	<img src="<?php echo $image_attr[0]; ?>"></a>

				<div class="flex-caption">
					<h3> <?php the_title(); ?></h3>
				</div>

		</li>
