When creating a Contributor Title, you can select whether the label appearing under the thumbnail image is the contributor's title or their organization.
Selecting a Contributor label
To select which label will appear under the Contributor thumbnail image, you need to navigate to the Contributor Title in which the contributor will appear.
If you already have a Contributors Title created, navigate to the Titles are in the Platform and select the Contributors check box in the right side of the interface.
Select the Conributors Title you'd like to modify, and once it opens, select the Contributors tab.
From this view, use the Thumbnail Metadata Display checkbox to select which label you'd like to appear under each contributor's thumbnail image.
Note that this settings applies to all items in the Contributors Title.
Once you have made the selection, be sure to hit the Save button.
