icon
Note that "icon" is sometimes misleading, and should be interpreted in the context of the entity. For instance, in Destiny 1 the DestinyRecordBookDefinition's icon was a big picture of a book.

But usually, it will be a small square image that you can use as... well, an icon.

They are currently represented as 96px x 96px images.

highResIcon
If this item has a high-res icon (at least for now, many things won't), then the path to that icon will be here.
