A few notes;
Copy the photoshop folder from the CD (you don't need the whole CD)
I renamed the folder and the MSI as they had spaces and brackets in it that I couldn't escape properly
Then you need to edit %Z%\packages\Adobe_Photoshop_CS2\Abcpy.ini with the details for your site
photoshop.bat
:: Install adobe photoshop CS2 :: URL|ALL|http://www.adobe.com @Echo off :: install photoshop start /wait msiexec /I %Z%\packages\Adobe_Photoshop_CS2\Adobe_Photoshop_CS2.msi /q
