Does not work on WordPress.com

This plugin is broken on WordPress.com hosting. I want to make this clear, that this is not a fault of the developer, though.

Jetpack (even with image optimization off) automatically messes with some of the thumbnails, which leads to the plugin’s offloading feature failing repeatedly. (From what I can tell, it adds the virtual:true flag to the image). Regenerating thumbnails doesn’t work.

I gave this a 3-star and not a 1-star because I migrated to a self-hosted setup, and it’s working fine.
