@obsolete29 Look at the use of images in news coverage while you're at it.
I agree with you that such images add little informationally to posts. They may serve other functions.
People are innately visual. They're (on average) far less literate. We process visual data readily, textual ... not nearly so fast.
An image may be iconic. Literally in the case of religious symbology. National symbols. Celebrities. Indicia of wealth or prosperity (from money to gold to other symbols of abundance). Tribal signals.
There's little question that images can increase engagement. They may simply be a part of styling or branding.
That said, something that's increasingly annoying to me is "mobile-first" designs of news sites --- ft.com, nytimes.com, and reuters.com all come to mind --- making very heavy use of images. I view these mostly on a 13" e-ink tablet, and all that the images do is crowd real information off the sites. It's a nuisance.
