Wordpress 3.3.1 not cropping featured image

Question

When I add a featured image to any post the image is not cropped but it is always displayed full size.

The media settings are ok...

even when I call <?php the_post_thumbnail(); ?> in my theme, the full image is shown instead of the thumbnail.

What I am doing wrong? It is probably my 30th Wordpress based site and I never had this problem before.

Thanks

Answer 1

By default, the_post_thumbnail() $size parameter is 'post-thumbnail'. You can set that by adding this line to your functions.php :

set_post_thumbnail_size(125,125,true);

If this still doesn't update your image's size, you may need to use a plugin like "Regenerate Thumbnails."

Alternately, you can set the image to use one of the Media Options-defined sized by passing a $size parameter to your thumbnail template tag like this:

the_post_thumbnail( 'thumbnail' ); // display post thumbnail with the "Thumbnail" size defined in Settings > Media.

Answer 2

Do you have add_theme_support( 'post-thumbnails' ); in functions.php?
