The short answer is No - it is not legal to reproduce a person's copyrighted work without their permission, whether on a website or otherwise.
You will have to prove the work did not have copyright protection [i.e. it was not original and was not created with some skill or judgement] or find another defence, such as the work is being used for research or private study, criticism, review or news reporting. Most publishers/authors are easy enough to find these days by email.
