b4 i photoread books i usually take about a minute 2 open the book in increasing page intervals of 20 pages or so and stretch the pages in opossing directions & gently so it wont close. this way, when i photoread i have easier time flipping the pages. try this while ur photoflipping. its simple & should give u better results (just do it gently so u wont damage the cover).
hope this helps.
