I had to go back and look at what I had. They were .indd files. That was some time ago. I haven't updated the book. I had started and did create a number of additional files to be inserted. My files are chemical structures created with ChemDraw. It turned out to be a tedious process to create the files, export them as eps files and insert them into InDesign. Then I had to adjust them so they looked right on the pages. I guess the way to find out is just try it. Right now, given the time associated, $25 is really nothing.
