auto cropping mosaic

[bahaha]

Hi, I have photos like this

Anyway to make xnview batch autocrop them and save them as individual files? I have lots more and I hate doing this individually.

Thanks

If images have same dimensions, there is:
1. <ctrl + u> batch processing>transformations>image>crop
2. Enter values for origin and region.
For a potato slicer effect, using Nconvert might need less repeating steps (since there is no chopping grid).
