Sorry, I withdraw my previous statement. It worked fine on my windows dev machine, but then I deployed it on our linux prod server and it started delivering blank images, so please don’t merge my code yet. Strangely, your latest version works fine on the linux machine, but not on my windows machine. I’ll let you know if I get it sorted out.

Thanks for incorporating my fixes, but it looks like you only incorporated some of them and now it seems to have broken the plugin for me. Please check the changes in these files as well:

adaptive-images-actions.php
adaptive-images-script.php

I was having the same problem and it was caused by a framebuster script in one of my site-wide include files. Thanks for the tip!
