Hi David,
Yes, needed images was a topic specifically raised, by the V&A staff. They would love to know where the "gaps" on Wikipedia or Commons are so they can target the programme, or look at releasing (or creating images/video).
I'm wondering if this needs to be part of a request page, similar to the image request list we started at the BM* (anyone want to set it up)? I can't promise a quick response but a good wish-list from our community would probably help the internal discussions enormously.
