I've got my fingers crossed this plugin improves my image responsiveness and I'm looking forward to when my hosting company moves me across to the new server that supports WebP - when they do I'm now ready!

hi Stacey,
I'm sure it will and when you have configured to 'covert images to webp format' in the ochResponsiveImages plugin it will automatically start doing just that when your hosting provider supports the PHP GD library with WebP support build in it.

regards,
Ruud.

And as a tip:
Lower the minimum image size that should be handled in ochresponsiveimages, to 200 so it will also handle the ones on your front page.
And when you have enabled lazy loading in ochresponsiveImages, you can switch it off in jch-optimize plugin : your visitors can then enjoy browser native lazy loading with no additional JavaScript being need for doing the same.
