Although, the image you used is copyrighted your use of it could be under the Fair Use exception to the copyright because you are using it for a review of the movies on Ramayana.
Hence it would augur well if you mention that you are using it under Fair Use exception under the image caption. That helps readers to understand that you are not in breach of copyright. That would also give you credibility as a professional blogger.
Ok I will keep this in mind
@devann please see the post now. I have made changes.
