When you open an article in your app, the app first loads every image within the article - depending on the size of the images this might take some time. To get quicker access to an article within your app you can install the BJ Lazy Load Plugin in your WordPress account. This plugin makes your app (and also your website) load faster and saves bandwidth.
How does it work?
BJ Lazy Load replaces all your post images, post thumbnails, gravatar images and content iframes with a placeholder and loads the content as it gets close to enter the browser window when the visitor scrolls the page. The visitor won't notice that there a placeholders, as they are replaced by the actual images just when he scrolls down the page.
