The only exception is CS2. Today, it is impossible to download Photoshop CS 6 full version for free without breaking a law. The only way to get the desired software which I can recommend is to buy a license version on eBay. As a result, you will get an official program. Of course, it is not supported by developers but, anyway doesn't have any bugs which you can come across in pirate versions. I have prepared several useful tips on how to get free Photoshop without compromising on important image editing functions. Your dream may come true. CS 2 is a very old version but it is still working well. The company shares it and Adobe Acrobat absolutely for free.
