Does anyone recall when in the game Geralt is thinking about Shani and there is a still shot of the two of them walking alone a seashore? I want to take a picture of this particularly moving shot as nowhere else including the Witcher Artbook is this scene shown. Any help would be very, very appreciated.

You can see all flashback pictures
here.
I assume you mean this scene.

And I'm not sure but I think it was somewhere during the Alvin quest in Act 4.

That's the one I was thinking of, too. Touching, as are many of these flashback scenes (even the ones you get when your Geralt has been a heel to somebody). Yeah, you get it early in the "Alvin" quest; and if you interacted with Alvin enough while he was living at Shani's, you probably got the line about "pick-up sticks" already.

Thanks for your help folks. I indeed found the flash back image I wanted, however, the image is extremely small and when I click on it, I keep getting an advertisment for The Witcher 2. Any idea where I could get a larger picture of this flash back image?

Have you checked my second link?
Anyway - see attachment.

Many, many thanks Paradoks the picture is just what I hope for!!!
