My problem is about images. InDesign CS5 changes the image resolution to 72 ppi during the EPUB export. It also renames all the image files. In CS3 and CS4 versions there used to be option to keep the image as original so InDesign wouldn't do anything for the images. In CS5 this option is gone and I really miss it. I used to edit all my images in PhotoShop and didn't let InDesign to mess up my images. Anyone else missing the setting for keeping the images as originals? Any idea is Adobe bringing this option back?
Here's a good article about InDesign CS5 editing the photos:
