The Link Properties - Categories dialog tells CommonSpot that if the page associated with at least one of the categories in the "Selected Categories" list, it will highlight the image within the image grid.
You can select more than one item in the list before you click Add or Remove. Select multiple items by clicking on an item, then Control-click on all others.
After you select categories, they appear beneath the Highlight image grid for specified page categories bullet item.
