Permission museums to publish their work?

[Meister]

Thank you for your feedback, clarify the truth has not yet happened. When you take the work of the museum to the exhibition, then you pay the money as it were, for her rent. This is one situation. Museum must formalize the issuance of reception work, to undertake these expenses, etc. But I'm talking specifically about the images. I understand that all rights to them belong to museums and only with their permission you can use images in the exhibitions or catalogs. Just because they do not give permission to reason perhaps they zahochut money. Prices, as I understand it, are taken from the ceiling. Another interesting museums I have anything to transfer to heirs with the publication of images? which laws can read about it? ready to do it and report back))
