Hi,

Thanks for getting back so quickly.
My understanding might be incorrect but the reason I wanted to optimize just the thumbnails was because we have a particular product page (using woocommerce) that shows our product thumbnails and the load times are very long. PageSpeed Insights recommends us losslessly optimizing the images and so I thought since the thumbnails are the ones showing, then I may as well just update those ones, as opposed to all of our images (9,000-10,000).
But then my question is does that mean if I regenerate thumbnails later from the original, will the new thumbnails be unoptimized again because it copies over all the meta etc.
Again, I’m happy to optimize the original images, and THEN force regenerate thumbnails if you think that would work? Would that then give me optimized thumbnails?

Thanks for your offer, I will contact you through your contact page as well.
Cheers,
