+'''Lazy load images'''
+Using the Wordpress plugin [https://wordpress.org/plugins/jetpack Jetpack], it is possible to enable lazy loading of images. That means, images only visible in the current view of the web browser are loaded. This will speed up initial page load.

+services.wordpress.sites."example.org" = {
+  plugins = [ pkgs.wordpressPackages.plugins.jetpack ];
+};
+</syntaxHighlight>
+After enabling the plugin, in the Wordpress admin interface go to ''Jetpack -> Settings -> Performance'' and ensure that lazy loading of Images is enabled. Note that Jetpack comes with a lot of optional modules which should be disabled if not used. On the same page go to ''Debug'' in the bottom menu and click on the last link offering the list of all modules. Disable all modules you don't need instead of ''Lazy Images''.
