Thank you for sharing. Unfortunately, I did have WP Optimize compress my images that had already been done by Smush before I read this. Things seem fine so I can’t tell if I’ve caused any harm through double compression. I would like to uninstall Smush and take care of compression – along with everything else – in WP-Optimize (I love one-stop-shopping and always try to minimize # of plugins wherever possible). Any advice about how to go about this safely?
