Home page always plays the trump card for a site! Depending on how compelling the home page is, a user decides whether to stick to the site or go on to other sites. Hero images in Drupal web design trends are one of the best ways to seek page visitor's attention and keep them glued to your site.
Though this technique has been prevalent since a long time, loading time and bandwidth issues made it a bad choice for web developers. With the recent evolution in Drupal development services, both these issues got eliminated and it has become possible for the developers to feature HD images in Drupal sites and attract the page visitors!
