14 million images, more than 20k categories, typically denoting prominent objects in the image, either common daily objects, or a wild range of animals. About 1 million of them also have <bounding boxes> for the objects.

Each image appears to have a single label associated to it. Care must have been taken somehow with categories, since some images contain severl possible objects, e.g. a person and some object.

In practice however, the <ILSVRC> subset is more commonly used.

The categories are all part of <WordNet>, which means that there are several parent/child categories such as dog vs type of dog available. <ImageNet1k> only appears to have leaf nodes however (i.e. no "dog" label, just specific types of dog).
