Actually, it looks like #20 is the same bug and has a pull request with a possible fix!

Maybe I got too excited there. Not sure the patch submitted is a proper fix.

I can't figure out how to check if it is present in older versions (Git n00b here). If I could find a link to an older version I'd be happy...

I too downloaded the zip package, with which the error did occur. I was running a version of MAMP which included PHP 5.2.11. I just upgraded to the latest version...

Sorry for closing and reopening. Like I said: n00b.

Thanks kbjr. This is what I got back: array(4) { [0]=> string(7) "/rgba(0" [1]=> string(1) "0" [2]=> string(1) "0" [3]=> string(4) "0.6)" }

That returned: int(4) bool(false)

Legend!

Good point. (Hope you don't mind me chiming in). I've been [disabling WordPress native responsive images](https://wordpress.org/plugins/disable-responsive-images/) on sites where I use this plugin.
