[Plugin: Promotion Slider] promotions do not show, i only see posts

Thank you for your quick response! I’m using twenty-ten. And I’ve replaced the default header image with my logo image which is very small, only 143 pixels wide. My slider image is 324 pixels wide. So I can disable the function that places the featured (slider) image into the header? Is that in the header.php file? Is there something in there I can comment out? My understanding of php is very rudimentary.
thanks!

Sure, just find this code in the header.php file:

// Check if this is a post or page, if it has a thumbnail, and if it's a big one
    if ( is_singular() && current_theme_supports( 'post-thumbnails' ) &&
    has_post_thumbnail( $post->ID ) &&
    ( /* $src, $width, $height */ $image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'post-thumbnail' ) ) &&
    $image[1] >= HEADER_IMAGE_WIDTH ) :

and replace it with this:

// Check if this is a post or page, if it has a thumbnail, and if it's a big one
if ( false ) :

that works– thanks!
