Have you tried exploding the images. They will then become rectangle faces and images will convert to materials applied to the faces, but they will look the same as the original images. I don't know if Vray renders images, but it will probably render the project after exploding them.

Go to search and type the name of the file, make sure yo select the "this pc" option to search, that works for me.

tankyu @TedVitale_CG it really work
