How do you get images for your hub when you have no way of knowing who the copyright holder is?

Many hubs here use unattributed images, some from sites that sell the items in question, others from god-know-where. Often it is impossible to find out whom the image belongs to, so you can't ask for permission to use. And often, public domain images are not what you need. How do you deal with this?
