What you are looking for is known as a "serial". It is illegal to share or circumvent copy right protections that were put in place by the software manufacturer. However, if you still feel you need to get a serial for Photo Shop, I would recommend you go to www.mininova.org and searching for it there. However, and this is a big however, do so at your own risk as many "warez" as there are called contain viruses and trojans.
