Asset Bank has the ability to display either promoted or recently added assets within a category, as well as on the home page.
To enable this feature in a category navigate to Admin > Categories and '' the category where you would like them to display. Similarly go to Admin > Folders to display promoted items in a folder. There will be 2 checkboxes under the heading 'Promote Items?', one for items that have been recently added to that category and one for items that are promoted and are in that category. You can select one or both of these boxes.
Once this is enabled an additional strip (or strips) will display under the category title containing up to 10 assets of the promoted or recently added assets.
