Please add the following domain to the wgCopyUploadsDomains whitelist, so that I can use GWToolset to upload media files from that domain. I have provided at least 3 example URLs to media files that will be uploaded with GWToolset.
When looking your examples, I've noticed they seem to be contemporary. Worried about copyright issues, I've asked Wikimedia Commons administrator Okki for a second opinion, he thinks some objects could be below the threshold of originality.
I then browsed the collection, and have seen a collection of affiches. It seems Atria is also a portal, and media files could be hosted elsewhere. For example, for an affiche I selected, the collection is at geheugenvannederland.nl and picture at kb.nl.
This was for a demo (upload to Commons beta) at the GLAM wiki conference this weekend. The conference is over and the demo performed with other data. So this request can be disregarded.
