No, Autoptimize (the free version) does not include Shortpixel’s “adaptive images” JavaScript (but AO Pro does) and instead relies on your theme outputting “good enough” responsive images in HTML with the <img srcset and sizes attributes.

Ok thanks. So to properly serve adaptive images I would need to use Short Pixel Adaptive Images plugin instead of SPIO?
And still serve next gen images from AO via SP CDN?
thanks
SPAI uses the Shortpixel CDN as well, so you can switch to that and disable image optimization in AO 🙂

Ok so with SPAI it handles next-gen delivery via SP CDN and it does the lazy loading as well as far as I’m aware?
If I use SPAI then I just need to turn off both image optimization settings in AO right?
Then I have SPIO optimising the images on server, and SPAI serving adaptive images loading in next gen from CDN also lazy loading – and just use AO for the files minifying work?
Have I understood all that right?
I would disable image optimization & lazyload in AO and you could also disable SPIO as SPIA also optimizes images so when you have both active, the image are optimized twice which comes at an extra cost and little or no benefit 🙂
