edit index.php of your theme;
after this line:
<p class="more"><a href="<?php the_permalink() ?>"><?php _e( ' ', 'blue_with_grey' );?> </a></p>
add:
<?php the _post_thumbnail(); ?>
[edit] typing error corrected
http://codex.wordpress.org/Function_Reference/the_post_thumbnail
and set a ‘featured image’ for each post
error occurs when i add <?php the _post_thumbnial(); ?>
Parse error: syntax error, unexpected T_STRING in /home/a3079790/public_html/wp-content/themes/blue-with-grey/index.php on line 15
From the sounds of it, you’re just trying to add an image into your blog post. Is that correct? Or were you wanting a thumbnail image displayed for each blog post?
I want a thumbnail image displayed for each blog post
The above example that was given had a slight misspelling. It should’ve read:
<?php the_post_thumbnail(); ?>
Alternatively, have a look at the first example given here:
