FTP location: images/interior-images folder
Naming convention: each image file should be named with the following pattern isbn13.01.jpg, isbn13.02.jpg, etc., for example, if 9780297843795 has 3 interior images those will have to be named:
9780297843795.in01.jpg
9780297843795.in02.jpg
9780297843795.in03.jpg
*where possible we would ask that images are no larger than 1MB
