Dear Martin, thanks for your input and contribution to the Biva articles. Wikimedia Commons is an online repository of free-use images. The work of Paul Biva is in the public domain in countries with a copyright term of life of the author plus 100 years or less. I've just added the template PD-art-100 to the Commons images for Paul Biva. There is no reason why the photos you uploaded cannot be used in the French Paul Biva article. The user that removed them for the Paul Biva article was not justified in doing so. They need not be published. My only recommendation is to use good quality images. Pictures from auction sales are allowed. The images you uploaded are in the public domain because they represent works of art painted by a French artist who died more than 100 years ago. I will see if I can find some nice works by P. Biva online, and I will upload them to Commons, then I will proceed to post them in the French Paul Biva article. Let me know what you think. P.S. I would love for you to upload more Paul and Henri Biva works some to Commons.
