So do I need pictures?

It seems everyone posts pictures on social media. Admittedly we ARE visual creatures and many of the pictures are of cats, but, I'm wondering, do you read more if there are pictures? Do the pictures need to be relevant? Like, here's my cat.

Not much to do with the discussion, but what the heck, he's funny when he does this. So visual posts have it over just words, even if the words are the important part. More cats, it seems.
