How much are the photographic pictures?

I'm glad to answer your question. The promotion of photographic pictures must be approved by the author, which has the relationship between economy and interests. The author's works are protected by law, and not everyone can use them unless they are their own pictures. To promote pictures, you can publish more excellent and unique works through various institutions, and merchants or enterprises may contact you when necessary. In fact, my work was not adopted, which is a pity! )
