Enabling Post Thumbnails

We have added our code to show the post thumbnails on the homepage, but at the moment nothing happens as we have not actually enabled the feature to work. Now open up the functions.php that we worked on before, and the below code should be added after your menu navigation code.

// Enable post thumbnails add_theme_support('post-thumbnails'); set_post_thumbnail_size(520, 250, true);

The code above is pretty self-explanatory as it spells out almost exactly what it does. The second line will add the support for post thumbnails in our theme, while the third line defines the exact dimensions of our thumbnail, which for this article, will be set at 520 pixels for width, and 250 pixels for height.
