title: How to display an image with the text before it and after it in the vertical middle of the image?
body: <p>On one of my sites, I want to display a simple image gallery with a "PREVIOUS" and "NEXT" text link <strong>vertically center-aligned</strong> before and after each image (respectively) so that my users can easily navigate between images.</p>
