The article is devoted to the study of spontaneous imagination role in the process of image-communication. The modern cultural situation is characterized by the increasing role of figurative elements in the processes of transmission and information exchange. This is particularly evident in Internet human communications. The concept of "image-communication" that emerged in the information age, on the one hand, means processing of visual signals and the exchange of images between communicants on the formal and technical level. But, on the other hand, it can be understood as a special existential channel of essential human communication. This channel is no less significant than verbal communication. According to M. Heidegger, spontaneity is a key existential characteristic of the human ability of imagination. The problem of spontaneous imagination is not limited only to an epistemological aspect but refers to ontological mode of human existence. This problem manifests itself in the phenomena of spontaneous images cooperation and competition that is independent of the subject in the context of the imaginary ontology. These processes are the imaginative factors for the intensification of cultural communication between different traditions.
