What are the rules concerning incorporating stock image elements into a website branding or logo?
From what I understand, IStockPhoto.com doesn't allow it. Are there any stock images sites that do? Is there a specific licensing option required?
Please note- I'm not talking about adopting a stock image as a logo straight up- just using it as an element in a larger logo or brand design. What I want to know is if there's any leeway there, or if logos must always be original art from the ground up.
