As a follow-up to our previous article, Add itemprop=“image” to WP Content Images, we thought we'd show you how to add itemprop=“image” to the Genesis Executive Pro portfolio archive. We use a modified version of that page on this site that is built with the Genesis Parallax Pro theme.
It's actually quite simple. In the Executive Pro child theme folder, you'll find a file named archive-portfolio.php. The source code for archive-portfolio.php is below. Just add itemprop=“image” to the img tag in line 37 as highlighted in the source.
