I want to create a new image style in Drupal 7, with a name like front_video_thumbnail. I want to use this size image on front page. I wrote code in template.php preprocess_page(), like the following one.
$img = theme('image_style', array('style_name' => 'front_video_thumnail', 'path' => $value['uri']));
$content =l($img, $node_url, array('html' => TRUE));
No image is showing, because no image has been created in the new style folder.
How can I make this new image style created in the style folder?
