Bug: Thumbnails in Plate display when in a read-only group broken

Reported by: cxallan Owned by: wmoore
Priority: blocker Milestone: OMERO-4.4.8
Component: Web Version: n.a.

With the move to using cached thumbnails in milestone:OMERO-4.4.7 we rely on all OMERO.web thumbnail requests being 96 pixels on the longest side. These 96 pixel on the longest side thumbnails are what are requested during Import and the only thumbnails we can have confidence in being there.

As in a read-only group no new Thumbnail objects can be created and linked to the Image this really must be the default. Furthermore requests for Thumbnails via the "direct" mechanism should be possible via render_thumbnail.

As a quick fix one can do the following:

However this has numerous side effects, not the least of which is that all thumbnails in every Plate view are now 96 pixels on their longest side rather than 64 pixels.
