I don't think so. That isn't what the person said. Their entire post was built around stripping down web design to the words. In fact, the author was very precise in the usage of the term "words."
This for example: "But the most powerful tool on the web is still words."
That blatantly is not the case in my opinion. Photos are vastly more powerful than words on today's web. That's why 3/4 of all the posts on Reddit's home page are links to imgur. That's why a gazillion photos are uploaded to and shared on Facebook every day.
That's why you can read about protests in Brazil all day long, and until you see the photos, the sheer power of the protest will not ring anywhere near as loudly. This has been true so long as photography has existed. Whether we're talking about the Holocaust and WW2, an atomic bomb going off, or a photo of a kitten or puppy, you name it and photos win 9 times out of 10 over words.
What would walking on the moon be like without photos (and video) to go with it? Would reading the transcripts have amazed the world like the imagery did? I say not even remotely. Imagine reading about a man standing in front of tanks in Tiananmen Square, versus seeing it.
Another side note to all of this: there are almost a billion illiterate people still, sadly. And another billion that are only partially literate. Nearly every one of them can understand imagery. Imagery also crosses languages, you don't have to understand Mandarin to grasp the Tiananmen Square protest.
