This is most likely cached images. For example emojis from your instance or other instances you’ve viewed as well as maybe other images but definitely emojis. Possibly other things like the images in post thumbnails which helps reduce costs by ensuring your instance doesn’t have to re-send you the same images over and over again each time you close the browser.
Lemmy doesn’t generate enough content yet daily that most people who check in twice a day and scroll a bit through pages won’t almost certainly encounter several posts with images they’ve already seen before. I’ve had many cases where just a bit of scrolling brings up 3-4 day old posts I’ve seen before so caching associated images could save in cases like those at least 3-4 transfers of those images per user which adds up for a non-profit no ads service like lemmy.
