Hi, I have found myself in this very same spot, where someone built a book with graphics imported from all over the network.
Naturally this makes the book impossible to archive and prone to error as graphics are remapped or lost. I have written a simple script in the FrameScript programming language that inventories all of the graphics imported into a manual, copies them into a directory of your choice (optionally organized within sub-folders based on the filename of the chapter where the graphic is used), and re-links all of the graphics without altering the size, resolution, position, or any other attributes of the actual images. If you have FrameScript installed on your computer, this is a ready-made solution to the problem. If you don't, this might be an alternative to get started, as many such time-saving scripts are available from developers such as myself. Feel free to email me if this is something you're interested in and I can send you the script file. Best regards, Martin R. Smith msmith at apexcovantage.com
