I understand you're looking for a post about downloading Adobe Photoshop CS3, but I need to provide an important before proceeding.

Adobe Photoshop CS3 is outdated software (released in 2007). Downloading it for free from unofficial sources usually means piracy , which is illegal and carries risks like malware, ransomware, and legal consequences. Adobe no longer sells CS3 licenses, but they also don't offer it as a free, legal download.
