I would like to start a website where people can discuss whatever they please. They will be allowed to upload images of the topic they're talking about. For example, a user writes a review on the movie Transformers and places an image of the movie poster next to her review. Heck, I'll giving you a live example right now. I don't own the Transformers franchise, yet I'm posting an image of it right here:

The main point of my website does not revolve stolen images. It is totally not like Imgur, for example, which is basically a large image hosting site of stolen images. The images on my site would be accessories to the textual content. My site would actually help give the copyright owner exposure. In the example above, I'm giving exposure to the Transformers franchise.
So, is it sustainable to create such a website? Even though it's illegal to use stolen images, do copyright lawyers generally don't care because it's actually helping their business?
