Make Flex-Slider show only images from specific category

I am currently using the iMagMag theme and wish to make the 2 other pages on my website look exactly like the front page, but displaying different categories. My ‘front page’ is a news page, then the second page ‘interviews’ and the third page is ‘features’. All must look identical but are essentially 3 separate blogs / categories. (If you are interested I am doing this because some pages on my website are standard HTML5 / CSS and when any of the above options are clicked – WordPress takes over!)

I have managed to make the posts display as I wish but ……

Part of the page is their built in Flex-Slider module which scrolls based on a category set in the slider settings within admin – this is currently set to ‘news’.

I have edited the PHP to include the flex-slider on the back pages but it obviously still showed the ‘news’ images on every page. To combat this I created a new “flex-slider2.php” file and attempted to change the code within there to point at a specific category.

Any edit I make to the $data part of 'category_name' => $data['feat_slide_category'] causes the flex-slider to show images from all recent posts! The ‘news’ flex-slider continues to work as it should but the other include needs to only show posts from that category / page.

This is the code for the standard ‘news’ flex-slider …. could anyone tell me:

1/ How to edit this code to show only images from the relevant category / page

2/ How I will over come the next problem …. the fact that there is only one “page.php” file (where I have included flex-slider2) but I essentially need 1 for ‘interviews’ and 1 for ‘features’ so I can show 3 seperate sliders?

<!-- .fluid_container-->
<div class="fluid_container clearfix">
   <!-- #camera_wrap_2 -->
  <div class="camera_wrap camera_orange_skin  " id="camera_wrap_2">
	<?php

							$flex_posts = new WP_Query(array(
							'showposts' => 5,
							'category_name' => $data['feat_slide_category']
						));?>
		  <?php while($flex_posts->have_posts()): $flex_posts->the_post(); ?>	

			<?php if(has_post_thumbnail()){ ?>

 				 <?php $image = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID), 'full'); ?>

					<div data-thumb="<?php echo $image[0]; ?>" data-src="<?php echo $image[0]; ?>" data-link="<?php the_permalink(); ?>">
 							<div class="camera_caption moveFromLeft">
  							   	<div class="list-block-slide clearfix">
					<h3><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></h3> 	

			</div>
 							</div>
					 </div>	

		    <?php } ?>

		  <?php endwhile; ?>

		  <?php wp_reset_query();?>

	</div><!-- /#camera_wrap_2 -->
</div>
<!-- /.fluid_container -->

<div style="clear:both; display:block;"></div>

This driving me crazy so any help would be greatly appreciated!
