Tested using OMERO.insight-ij-5.1.0-511-eee50ab-ice34-b483 and merge build bioformats package from today. Trout user-3.

Cropped images are saved back to OMERO as OME-TIFF as expected.
Good to merge.

It is interesting to note that this whole workflow gives a way to circumvent OMERO permissions by opening a read-only image belonging to another user and then saving it back to the server as your own image. Something to bear in mind down the track,

Thanks, @gusferguson. Merging.

(At the risk of misusing this PR for a discussion, is the workflow not something a la deep copy? So I don't know if I would really consider it circumventing the permission system, but it does allow copying, just when data duplication.)
