1. Go to C:\Program Files\Adobe\Adobe Photoshop CS2 (or wherever you put Photoshop)

2. Open Photoshop.dll (right-click> Open With...> Choose Program...> Notepad).

4. Scroll down untill you see a lot of s p a c e d - o u t text.

5. Read what you see (I'll give you a dollar if you can read all of it) until you reach " E N D = * * * * * E N D * * * * * "

This may (and I mean may) be accessible through Photoshop itself. From what I think, this can be accessible through the About Photoshop area, but there may be some other way...
