The group screenshots are each collection reward set. A female human rogue provides a sizing comparison for the item's default size. Very large items (trees and rocks) are repeated sized to as small as they can be made. Some items are also shown in an alternate view (i.e. table tops). Lower on the page are screenshots for individual items with their names.

The individual screenshots are from the preview window from the reward
preview. For very dark items on the black preview background, I have
lightened the screenshot to make the items more viewable. You can use
the
View Reward button on the Achievement window in game to twist and turn
the items to see other angles.
