Hyperlinking images on posts to permalink

Question

i have this site with only one image in each post.. how do you turn the posted image to hyperlink to the permalink? Most images are from an external source and is just automatically embedded on each post using a plugin that I use. There are a lot of posts on my site already and it's next to impossible to manually edit each post to link the each image to the post's permalink..

I checked the index.php of my site.. I saw a line for "the content" and when I added an "a href" to it linking to the permalink, it just doesn't work, im not sure why..

please help. thanks!

Answer 1

If they are featured images or post Thumbnails U can add this code in functions.php to link them

add_filter( 'post_thumbnail_html', 'my_post_image_html', 10, 3 );

function my_post_image_html( $html, $post_id, $post_image_id ) {

$html = '<a href="' . get_permalink( $post_id ) . '" title="' . esc_attr(   get_post_field( 'post_title', $post_id ) ) . '">' . $html . '</a>';
 return $html;

}

If U need to add theme support then refer to this link

http://codex.wordpress.org/Function_Reference/the_post_thumbnail

Or else if U don't prefer to add this code just find files like

Loop.php , content.php,-main.php,index.php, home.php

And then just press F3 in this files and search for

 the_post_thumbnail

And Permalink that code

And if U don't find that then it may possible that ur themeay using tbe_content for it
