Two days ago I called a museum in Sweden about a painting. The person I talked to we came to talk about copyrights of images, pictures etc. This woman scared the sh-t out of me! At least in Sweden you could be sued for a substantial amount of money if you use a picture you have found on the internet without the permission of the holder. This apply to Sweden but I wouldn´t be surprised if similar copyright laws applies to other countries. So be careful.

Usually pictures like that *which are on the internet* are protected and you cannot download them without the permission. Anyway, thank you for the warning.
