Affective Image Database (AID; Grühn, Kapkin, & Sharifian, 2015) contains 7,232 images, which were categorized into a two level hierarchy. The main level consists of five groups of images: Animals, Humans, Objects, Indoors, and Outdoors. Each main category is divided into subcategories. All images in the AID were rated on valence and arousal using 7-point versions of the Self-Assessment Manikins.
