Been great for me

This plugin has been great for us. A further benefit of using the pro feature is that I can use it for non wordpress optimizing too, via the web utility site!
I found that it even works when I use Product CSV Import Suite for Woocommerce, as long as I post those images to a server and use urls to pull them in, rather than the other method of uploading the images via FTP. Hopefully this tiny workaround will help woocommerce product csv importers.
Great plugin and service.
