Handbook discrepancy: <top-level>/<batch> vs. <top-level>/images/<batch>

The Cell Painting Gallery and the Profiling Handbook specify different nesting structures for images.

Should we try to resolve it by modifying the handbook to suit? Note that when [deciding](https://github.com/jump-cellpainting/aws/issues/53) the folder structure for the gallery, we did start with the handbook structure and then modified it because we felt this new structure (used in Cell Painting Gallery) made more sense.

It's not mandatory to resolve this discrepancy because it can easily be handled during sync.
