I love your picture and I was wondering if I could use it on a website I am designing for the German society of Immunology? We want to make a website called "Immunologie für Jedermann" which means immunology for everyone. It is a free website for anyone who wants to learn more about immunology. There will be a book about immunology for sale at cost on the website - however the contants can be read online for free.
Can we use you picture?
