ImageSynth creates it's own directory of files. Mine created a directory as "Photoshop CS" I found all the DLLs and everything else I needed in there. I then put each file in the coordinating folder in my Photoshop 7 and everything works fine.
So it Like this:
**C:Program FilesAdobePhotoshop CSPlug-Ins
Then I copy all those files to this folder:
****C:Program FilesAdobePhotoshop 7.0Plug-Ins
**Let me know if that works!!!

I would rather be Politically Incorrect,
Then have Politically Correct-Incorrectness!!!
