redirect slideshow from featured photo to desired

I am using a theme called Nomad. It looks like the slideshow is a jquery slideshow.
What I would like is a slideshow that goes to pictures I select, versus one that uses the feature image.

Here is the code from the “index-slide.php” editor

<div class=”slidebox”>
<div class=”flexslider”>
<ul class=”slides”>
<?php
$slide = get_option(‘nomad_slide_cat’);
$count = get_option(‘nomad_slide_count’);
$slide_query = new WP_Query( ‘category_name=’.$slide.’&posts_per_page=’.$count.” );
while ( $slide_query->have_posts() ) : $slide_query->the_post();
?>

• “><img class=”slideimg” src=”<?php bloginfo(‘stylesheet_directory’); ?>/timthumb.php?src=<?php echo get_image_url()?>&h=300&w=720&zc=1″ title=”” alt=”” />

<?php endwhile; ?>

</div>
