PageSpeed Insight Opportunity for mobile - properly size images on mobile

Hi all. I have a site with an image carousel, images sized at 1000px wide. Google PageSpeed is flagging this as an issue for mobile, but I don't see any way to customise image size for different screen widths. Is there a way to do this? Thank you in advance.

Is it the dimensions of the images or the file size that’s being queried?

It says:  

Properly Size Images


Serve images that are appropriately-sized to save cellular data and improve load time.”

The images are 1000px wide as they need to be nice and big for widescreen. The only thing I can think to do is hide the main carousel on mobile and make a different version with resized images. But that’s quite a faff, and won’t Google crawl everything anyway, even hidden stuff?
