Hey Jacob,
First of all. Thanks for publishing this plugin and for supporting it. I think this is the solution I need for my website.
I experienced the issue with the broken images upon installation. I think this may be due to my host: wp-engine. That being said, I used the fix (‘{plugin-url}/slir/index.php?r=’) and it seems to work when the images need to be responsive (smaller width screens) however it’s created black background on all of my images when the screen size is normal.
Here is my staging site where you can see this:

Here is my production site where the plugin is disabled.
Any help here would be much appreciated.
Regards,
Jonathan
