As part of a migration, we import 30.000 images over plone.restapi. The site has about 28 different scales (the sense of this number is a different discussion) but this wastes a lot of time and space during the migration.
- is there a way to defer the creation of image scale until they are used?
- is it safe to clear the underlaying annotation (ScaleDict)? Will Plone re-create one scale or all scale if requested/needed?
