Okay,

From the sounds of it there could be 2 possible solutions.

1) If the watermark is always on a particular layer then the script could just see if this layer existed

2)The script knows what the watermark looks like, so it looks through all the pixels of the image, one by one, to see if the watermark exists. It should be able to find it easily if looking on HSB scale, as only one of them would be changing. Basically the script would look to see if the pattern of the watermark existed and test it to ensure it is the same size. If it is then the match has been found.

The problem with (2) is that looking at pixel details via scripts is very slow. So if this was the only option, it would be best to create a standalone application.
