Preload background image

[stromb0li]

I was running a lighthouse test and noticed a couple images are flagged for performance issues since I'm not preloading them.

A few of them are background images I use on about 80% of page views. Given it doesn't cause a layout shift, should I still preload them? If so, is there a best practice for injecting the link tag into the header tag of the page?
