Support » Themes and Templates » Post Thumbnail Problem

  • I’ve been trying to work out all day how to change my post thumbnail image size + alter the post excerpt position. I have been experimenting with the first post on this page as you can see below.

    I have inserted the image through edit post>featured image. But I would like to have the thumbnail image larger, plus the excerpt below the thumbnail.

    I have tried altering the thumbnail size through setting>media. But this did not work. I can’t stop the two from overlapping either, have tried various ‘float bottom/top’ and padding but I can’t get it to work.

    So ideally I would like a larger thumbnail image for each post, with the post excerpt below.

    Any help would be great!

    Thanks, James

  • In your theme, you an either assign a size manually to the_post_thumbnail by replacing ‘thumbnail’ with an array of integers (width, height).

    The better method is to register a new size in your functions.php file, which uses add_image_size();

    Then replace ‘thumbnail’ with ‘newsizename’. You will, however, need to regenerate your images. See this plugin for easy thumbnail regeneration.


    Okay so I place this in functions.php <?php add_image_size( $name, $width, $height, $crop ); ?>

    Then edit it to this for example

    <?php add_image_size( ‘newimagesize’ , 250, 250, true ); ?>

    Is this correct? What should I do next? Where do I replace ‘thumbnail’ with ‘newimagesize’?

    Wherever in your theme your thumbnail is appearing, it ought to be using the_post_thumbnail() function. That is where you should replace the image size. Remember you will need to regenerate your thumbnails for existing (already uploaded) images to work with your newly defined image size.
