TL;DR - Would photographs that I've captured and displayed on my personal photography website be considered commercial if I'm not selling them? I would purely be selling my general photography services, or other photos that I know I can sell without any concerns for permission.
I'm currently building a photography site showing photos I've taken. I would not be selling them for purchase - they're purely to demonstrate the composition style I like and the types of photographs I've previously captured. But I want the site to be used as a way for people to pay for my services (e.g they wanted to use me in the future for their own personal shoots...)
If I had a photo I'd previously taken (e.g such as in a museum, and the museum requires permission for commercial still shots), would placing that photo on my site be classed as commercial, even if I'm not selling it?
