How to use Disney images legally?

I'm curious to know, how exactly can one go about using Disney images legally? I understand that Disney has a reputation for fiercely protecting their intellectual property, so I'm interested in understanding the proper channels and processes for obtaining permission to use their images for personal or commercial purposes. Is there a specific form I need to fill out? Do I need to pay a licensing fee? I'd love to get some clarity on this topic, as I'm eager to use Disney imagery in a respectful and lawful manner.
