Hi, can you please tell me how to optimize images for mobile? For eg, I uploaded a 300kb image for homepage which is okay for the desktop, but when displaying on mobile I would like it to be scaled down to one of the smaller sizes. Is it possible?
I use media upload to upload images and wp-smush plugin to reduce file sizes.
This is already done by the wordpress itself in version 4.4 .
Now all the images that is added to page using the medial uploader will be optimized automatically .
But that is not happening in my case. I'm using W3TC and AWS CDN. Could it be because of that?
As mentioned in the above reply, WordPress 4.4 provides the optimised images.
