The image doesn’t look like a photo. The meme is about porn. Digital images can contain large areas of repeating patterns (uniform color areas for example) that can be compressed losslessly pretty well. Even slight noise from an image sensor can block that kind of compression pretty well.

With a picture from Unsplash:
Three files of the same image: A png (15.7MiB), a bmp (28.8MiB) and a bmp.zip (16.4MiB)ZIP compression of bmp is worse, but still compresses better than png. Here are the files

Fascinating. That’s much more than I expected from the theory. Thanks for taking the time.

Png is lossless

You’re right. png can be lossy but that’s uncommon in the wild.
