Images not showing up on User Submitted Posts

Seems like many users are having a similar issue as I am. Basically when a user submits an image, the image does not automatically show up in the post.

Yes, I have read the README.txt and understand that the image doesn’t automatically show up and I have to add some code to my theme files. I am half way there now. I’ve tried adding the code to the index.php and single.php, the image shows up BUT it shows up above the post. It almost looks like the image is not part of the post. How can I get it to show up either above or below the post content?

Here is my code:

<?php if ( have_posts() )  : ?>

				<?php twentyeleven_content_nav( 'nav-above' ); ?>

				<?php /* Start the Loop */ ?>
				<?php while ( have_posts() ) : the_post();  ?>

				<?php if (function_exists('usp_post_attachments')) usp_post_attachments(medium); ?>

					<?php get_template_part( 'content', get_post_format() ) ; ?>

				<?php endwhile; ?>

Is my code wrong or what theme file am I suppose to edit? Thanks in advance!
