Get File reference into multiple container fields

[Carl Smith]

I have a large database of thousands of books and have now been given hundreds of image files (that I've been able to relate to my book database by creating a separate "image path" table which stores my book ID number and the file path where the related image is stored. The images, however, have been named by the supplier so they do not instantly relate to my database) and I want to somehow, by using the book ID relationship, store the path references in my new container field in the book database so that I can view the image.

As I'm relatively new to FP8 and container fields I am hoping someone may be able to help. I hope so!
