I'm planning on starting a mass upload from Cooper Hewitt, based on a VP request. Images all appear to be in the domain https://images.collection.cooperhewitt.org. If other formats like videos of objects are suitable for upload, this would be an additional request.
I know these requests take up to a week to get implemented, so raising before I have an example set of uploads done using local uploads though I have the CH API working and have the metadata mapping half done. I would expect to be able to link to examples in a few days if this is needed. As I'm experienced, you may want to skip that step, especially as my upload speeds from home are totally lame. :-)
