You need to override the item.php file
getk2.org/documentation/tutorials/174-templating-with-k2-and-the-concepts-of-sub-templates

Then you need to move the title's block github.com/getk2/k2/blob/master/components/com_k2/templates/default/item.php#L42-L63 under the image. You can identify the image block from the comments.
