If there are enough photos they can tell a story, but a couple photos just don't unless you just happen to catch something amazing. Even the most iconic photos of all time went into a magazine with a story and the photo was supporting the story. Then in turn the story made the photo iconic as it became engrained in the minds of those who read the story. They may not remember the words, but the image lasts because the words touched them.

As someone who took many photography classes I've met enough people who felt their photo told all, but even they took the time to explain where the photo was taken, when it was taken, and all of the details of the lenses and camera settings when they displayed their works. Sadly those who felt this way, not one has ever "made it" as a photographer. The ones who have done well that I met over the years all understand the need for story telling and how the photo draws people into the story and even becomes the story once others have read the story. The image is lasting, but the words were needed to properly frame the photo.

The word requirement at 200 words isn't hard to hit and removes what most on steemit see as low quality posts. Side note this simple reply is long enough that a post would qualify. Seriously takes less then 5 minutes of effort.
