The top photo is by Rob Lang, you would need to contact him. I imagine re-posting on the internet is fine but using it in any publication or anything that you’d make $ off of would require permission from the photographer. I have no idea who took the lower photo. I don’t claim any rights to these pictures, there’s just bouncing around all over the internet.

Hi! I was wondering if I could use this pic. I´d like to know if it was right free
