This is the page Google gives the most bad marks for loading slowly b/c of images...
Today WebPage Tests says my images are not compressed. It also tends to say they are not progressive jpegs.
I laboriously used GIMP to make progressive jpegs prior to using quick and lovely (if it works) Smush.it
In WordPress I can't find Smush.It when I want to use it on an individual image. There is nothing, that I can find, in my media library that allows me to use Smush.It then and there.
How can I make sure my images are progressive jpegs, so Google stops dinging me?
