Domain whitelist permission please. I am a librarian at Université Laval library. I would like to upload a collection of pictures (that you can see here https://kalos.bibl.ulaval.ca/digital/collection/p22018coll8/search) from our library. You can see an example here: https://www4.bibl.ulaval.ca/spbar_kalos/archi.qc_1/11-d.na.civile-75-1878.jpg.
