Use PSD files as templates | Scene7
I want to create PSD files to generate basic templates automatically on upload to Scene7 Publishing System (SPS). What versions of Photoshop PSD files does SPS support?
SPS supports PSD files created in Photoshop CS4 and later.
It's possible that PSD files created in earlier versions of Photoshop will work, but Adobe hasn't tested them, and they're not supported.
