Can we not give you credit?

I was just contacted by a media company representing a Japanese band asking me if they can use a photo I took in a video they are creating.  They also asked if they could not give me credit for using it.  I have had my works ripped off before but no one has ever asked in advance to do it.  I am going to say yes just because I think it is cool they asked me first and because I want one of those shirts that say “I’m huge in Japan” and I want to wear it with some integrity 🙂
