how can I call a posts featured image in any template?

Question

I would like to call specific images in my template from the posts and pages of my choosing.

For example I want to these featured images on my home page;

• About page
• Project post
• Another page

I have used the_post_thumbnail() on my archive pages and to call the image to it's particular post or page. But i can't find any information about calling specific featured images.

Does anybody know?

I think you are looking for get_the_post_thumbnail() which takes accepts the post ID as a parameter. get_the_post_thumbnail() generates the entire image code. There is no need for you to try to create your own <img> tag.

It is used as follows:

echo get_the_post_thumbnail( $post_id, $size, $attr );

So for your example, remove the following:

<img src="<?php echo get_the_post_thumbnail( '25, medium' ); ?>">

and replace with:

echo get_the_post_thumbnail( 25, 'medium' );
