Wordpress 3.2
Ata 3.6.7
I would like to display only excerpts on all pages. I have set theme options to show only excerpts on all pages and I have changed the thumbnail size to 150x150 in Ata theme options and in Wordpress media settings. I have cropped all images (applied to only thumbnails) so that heads won't be cut off when the thumbnail shows up in the excerpt. However, after having done all this, the thumbnail images that I cropped, don't show up. There is a thumbnail, but it is the uncropped version. I have tried everything... I tried thumbnail editing with NextGEN gallery and it does the same thing. I also use Regenerate Thumbnails... did that and nothing changed. I changed to the Twenty Ten and Twenty Eleven themes and thumbnails work fine (cropped thumbnail shows up). After reading Wordpress Codex, I noticed that the information below is not in the functions.php file. Do I need to add this for the "cropped" version of my thumbnail to work? Please help! I have been struggling with this for weeks and have read everything I can and have found no solution! I assumed it would be easy to crop an image, apply it to a thumbnail and have it show up in post excerpts.

From Wordpress:
Themes have to declare their support for post images before the interface for assigning these images will appear on the Edit Post and Edit Page screens. They do this by putting the following in their functions.php file:
if ( function_exists( 'add_theme_support' ) ) {
add_theme_support( 'post-thumbnails' );
}
This is what I found in Ata functions.php:
if ( function_exists( 'add_theme_support' ) ) { // Added in 2.9
// Since 3.4.5: WP 2.9 thumbnails support:
add_theme_support( 'post-thumbnails' );
if ($bfa_ata['post_thumbnail_crop'] == "Yes")
set_post_thumbnail_size( $bfa_ata['post_thumbnail_width'], $bfa_ata['post_thumbnail_height'], true );
else set_post_thumbnail_size( $bfa_ata['post_thumbnail_width'], $bfa_ata['post_thumbnail_height'] );
add_image_size( 'single-post-thumbnail', 400, 9999 ); // Permalink thumbnail size
// Since 3.5.4:
add_theme_support('automatic-feed-links');
}
Thank you in advance!
