We’ve moved from AVC to HEVC and VP9 relatively quickly, but for some reason images are stuck in JPEG, PNG, and GIF despite newer formats like JPEG2000 and HEIC having been around for years? Videos are just images displayed very quickly, shouldn’t the adoption pace of image/video formats be similar?

It’s pretty much the same reason most knives are made of steel.
Steel has been around for many centuries, and there are better materials available, but steel does a good enough job, and there’s no real need to change, except for some specialized applications. Likewise, storage space and bandwidth are cheap and plentiful enough that it doesn’t usually matter what format images are in. A 120k image file isn’t that much of an improvement over one that’s 200k, because they’ll both take a fraction of a second to send, and you’re probably putting in on a hard drive that could hold a million files that size, so it’s a drop in the bucket.
With video it still matters, because the file sizes are enough that it makes a difference in sending and storing them. Some day soon, that won’t matter either, because storage and bandwidth will be even cheaper and faster. Then they’ll settle on a couple of formats that look realistic enough, and those will be the .jpg and .png of video.
