I tried that but I pu the code like this:
if (function_exists('the_post_thumbnail') AND !function_exists('tfe_get_image')) {
if(has_post_thumbnail()): ?>
<a href="<?php the_permalink() ?>"> <?php the_post_thumbnail(); ?></a>
<?php endif; ?>
<p><a href="<?php the_permalink() ?>"> <img src="HERE THE LINK OF THE PIC" alt=""></a></p>
<?php
}
the_excerpt();
}
echo $after;
}
But it puts the picture even if it already has a featured image. Also it shows on the top of the excerpt no of the left side as it would look with the featured image set manually.
1.How it looks if I put it manually:

2. How it looks when I added the code:

3. How it looks with setting the featured image manually.
