Permalink my thumbnails & Title

What you’ll need to do is edit loop.php (make a backup first!)

Line 24 reads:

<h2><?php the_title(); ?></h2>

This is what displays the title of a post.

Change this to:

<h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>

and this will link the title of the post to the individual post page.

Post thumbnails are set to link to the large versions of the images, as per line 18 of loop.php:

<a href="<?php echo wp_get_attachment_url($thumbID); ?>" rel="gallery" title="<?php the_title(); ?>">

To change this to link to the individual post, change line 18 to:

<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>">

These steps will also need to be repeated with loop-category.php and loop-archive.php to change the links on category and other archive pages.

Hope this helps!
