I uploaded team member photos to media under their names and added a title and description. I then created a new portfolio item, assigned a category, made the title the team members name and set the featured image to their media photo. I then created a Team Member page with the following body and default settings: [portfolio columns="3" categories="6" sortable="0" max="-1" show_description="1" show_read_more="0"]
The page shows their photos with title, but not description. I also tried the code without show_description, because the default is TO show it.
Excerpt worked and so did the main content on the portfolio item (though it ignores text formatting like Header 2 or color entirely for some reason). I assumed that the portfolio tag would display the portfolio items on the page with the title and description from the featured image, not the portfolio page itself.
