[Plugin: Riloadr for WordPress] Where to load images?

Hi, sorry for the late response (WordPress didn’t e-mail me :/ ).

You do not need to specify anything, as the plugins script will itself add the “riloadr” html class to all image elements. When the site loads, the javascript will change all image elements to find the image-size (from your themes defined sizes, or the Riloadr ones) that best fits with the size of the viewport of your browser.

So, all you really have to do is what you’ve already done. If the image you added to your post has various sizes, Riloadr will find the one best suitable for whatever size your currently viewing the post in.
