This portlet behaves like collection portlet, but shows the contentleadimages and the title of each item. If the item has no lead image but has a image field (like News Items, for example) then this field is displayed.
This portlet has an extra option to display start dates instead of publication dates.
Another extra option can be used to choose the scale of the images.
To install just add collective.portlet.contentleadimage to your buildout's eggs and go to the products section of Plone's control panel.
