After running the Google PageSpeed Insights several times, one of the first things I get "dinged" on is "Serve images in next-gen formats".
I read the directions: I took the image into Photoshop and saved as JPEG 2000 but when I replace that image in my HTML, no images show. This is true for both my local machine and in Production.
Is there something I am missing?
- Changing the File format from .jpg to .jpf (in Photoshop)
- Replacing the HTML (e.g. image2.jpf)
Thanks for your help.
