For any couple of several weeks Now i come with an wordpress-based website for iOS Application reviews. (Nearly) All articles begin with a picture from the application. This images are visible around the primary page, but around the category-view individuals images are hidden or otherwise there. I want this category page to alter between iOS and Mac OS Applications and it might be nice when the images could be proven there too.

Primary page: Category-page:

How do i change it out? Could it be triggered by WordPress or even the Theme? Thank you for solutions!

the code of groups.php:

<?php /* Start the Loop */ ?>
            <?php while ( have_posts() ) : the_post(); ?>           
                <?php get_template_part( 'content', get_post_format() ); ?>
            <?php endwhile; ?>

And here of content.php (where images are proven):

<div class="entry-content">
            <?php if ( has_post_thumbnail() ): ?>
            <a href="<?php the_permalink(); ?>"><?php the_post_thumbnail('thumbnail'); ?></a>
            <?php endif; ?>
            <?php the_content( __( 'Continue Reading &rarr;', 'bugis' ) ); ?>
            <?php wp_link_pages( array( 'before' => '<div class="page-link">' . __( 'Pages:', 'bugis' ), 'after' => '</div>' ) ); ?>

It's triggered through the theme. Should you try looking in your styles folder and search for (In my opinion) archives.php. You will want to add something similar to this in which you want the look to appear:

if ( has_post_thumbnail() ) { // check if the post has a Post Thumbnail assigned to it.

You are able to try looking in your index.php file to determine what it is set available online for, and also you could most likely just copy the code.
