Download Adobe Creative Suite 2 legally for free from Adobe

Adobe is giving CS2 away fro free from their website. Including Serial Numbers - but no support. It works even on Windows 7 and current Mac OSX - but you have to fiddel around a bit.

But still - Photoshop CS2 and the Professional Acrobat etc. is worth it.
