The index value must be a zero-based position for the substring to  
begin.  I think you want to add a step using indexOf()


str = "C:\Dokumente und Einstellungen\Johannes Breu\Eigene Dateien
\Platz\Images\IN12/Image0006.tif";
ix = indexOf(str, "Images");
n = substring(str, ix);
print(n);

I just noticed that on my Mac OSX (ImageJ 1.41) the forward slash  
disappears but it might work on you Windows machine just fine.

Cheers,
Ben
