I have used the Smush Pro plug-in to improve the image portion of the performance score of this website. However, the score only increased by 1 and thus still remains very low. I have tried resizing the images recommended in Hummingbird plug-in, but it does not seem to have made the change. I scaled the images in wordpress, but when you view the code of the wordpress site, the image pulled is still the larger file. Does scaling through wordpress not work?
