Collection: Here you can search in the Royal Armoury, Skokloster Castle and Hallwyl museum collection online database. You can find information on museum collections, images of objects and museum environments and the people who have made, owned and used the objects. These include paintings, weapons, furniture and costumes but also the accounts, books and everyday objects.
The images are free to download and use. The photos are tagged with Creative Commons licenses and copyright information, see the connection to each image.
Since March 2013 our entire image archive is available on the Internet. All 40,000 images are published under open licences, about a third of them in high resolution. Now you can use all our images, free of charge.
Every academic author knows the pain of getting the image permissions for their articles, books and other publications. It takes a huge amount of time, money and frustration. However, many institutions will allow free reproduction of images of their collections for academic publications if they fulfil certain criteria, depending on the institution.
This site lists those generous institutions providing open access to images in various ways, and their conditions. Please drop an email if you know of more to add or contact me on Twitter @FourRedShoes.
