Hi,
As in the title - i’ve saved my Jpegs as Progressive in Photoshop but I’m getting an ‘F’. I’ve renamed and uploaded different versions to avoid caching issues but still the same. I know I’m doing something stupid but would be great if anyone has any ideas.
Many thanks.
Do you have a link to your test results?
Hi - thanks for reply. I think it’s maybe the thumbnails in the Wix gallery that aren’t progressive… while the file size files are. That’s what WebPageTest is pulling out as non-progressive…
The only thing that makes sense to me…
It’s hard to tell for me without your WPT test results 
But if those thumbnails are generated by Wix (i.e. outside of your control), then that could be it.
