Thanks for the reply. It's polite (and also the law) to ask permission first. Otherwise you are just plagiarising someone's work for your own financial gain, which is illegal and filthy behaviour.

Thanks for taking the work down. For the record, I am a nice person, but my work is my livelihood and I take my copyright seriously. Had you asked me first, I would certainly have been more amenable you using the image. As the situation stands, I think it's a disgrace.
