hi, amyg.
i actually ended up exporting the whole thing to epub then renamed to zip extension so that i could swap out the image files because my book came out looking faded and sun-baked after compiling in ID. i checked the dimensions, ppi and file name before swapping and made sure the code matched the contents of the Image folder. long story short i spent several days making sure that part of it was good.
thanks for your time & input,
julie
