Now you can create custom srcsets or turn off webp support, and Luna will handle everything for you automatically!

hugo-theme-luna/exampleSite/config.yaml

Lines 367 to 371 in 7a88ddc

	autoResize:
	- 640
	- 1080
	- 1440
	webp: true

You can set it up like Instagram

Note: If you need to handle too many sizes, hugo will be very slow to generate the first time.
