Looks good to me in general. I think catching the non-overwrite error would not be needed in the task anymore if we set overwrite=True this way.

I wonder whether we should do the same for the MIP task: It doesn't rely on an image already existing, so I see more of a reason to keep the overwrite parameter there for the moment. In Fractal itself, it's always run with the init function which checks whether the plate & well already exist & would overwrite them, but there could actually be a use of this function standalone from its init? I also haven't tested whether the plate overwrite will actually overwrite all the content of the zarr images. I assume so, but haven't tested it.

Agreed. At first I thought we could keep it anyway, just for safety, but it should be unreachable when running through Fractal. I now removed it.

Note that if that error appears, for whatever unexpected reason, the task still fails (just with a slightly less transparent error message).

Looks good to me, let's merge this! :)
