When you insert your pictures and such, are you remembering to 'embed' them in Word? Sometimes creating a specific area for those items within your document will help 'anchor' them. If all else fails, go to the help area of Word, (F1), click on 'contents', and then scroll down to 'graphics and diagrams'. Perhaps this will help you get your added items to stay where you want them as well as to help with the formatting of the pages.
The issue is not creating the report in a genealogy program, it's finding a word processing program that will allow me to edit after moving the info from from the genealogy program. Then adding many photos and documents. I'm using Microsoft word but experiencing problems with photos and captions moving to other pages after I have saved the file. The book I'm publishing is only 100 pages and my next book will probably be closer to 350 pages. I need a more dependable word processor program or a better understanding of Microsoft Word!
Have you thought of doing a narrative type report in RM? It would be a good base to start your book on, since you would pick the ancestor and then do a 'modified register' of that person for whatever number of generations you would like. Once you have created that narrative, save it to your computer as an ".rtf" type of file. Then go into your word processor and open it up. You will be able to make any changes you want, including adjusting any sentence format so it reads the way you want it to, as well as add pictures and other documents where you would like them to be, create the index, bibliography and even your title pages.
While I may offer step-by-step location of various things in a book if asked, I do not lend out my books either. If the person is a newbie to the product, I strongly recommend the purchase of the book so they can make notes, etc in the margins or highlight various things they find helpful.
