Problem with animation of a picture of famous person (historic painting)

Hello,

We have bought your Advanced Plan, to do an animation for a corporate Film for a customer of ours. We have two images with a certain person that we want to animate using your softwate. But when uploading the image, the site blocks it because it is a "famous person". We confirm to be in the possession of the rights to use this image (an oil painting from the 19th century) in the project we are working on. As our customer ist the owner of that painting and alos the owner of the copyrights. The Painting was created in the 19th century (We`ll attach the certificate of this company.

We have written already two times, but didn`t get any solutions. What do we need to do to be allowed to work on this and animate it?
