Changing image styles in a node view (Drupal 7) In the node view of my custom content type I would like the image to stretch across the screen or at least be centered.  As can be seen in the below screenshot currently the image does not get resized and is left justified.  Would this be done through theming or some other means?
You can manage image-styles under


  admin/config/media/image-styles


and then use these styles to show up in your node view. Settings can be found on the "Manage Display" tab of your content-type. There's a little gear on the right side of the field row...
