Otco,
I'm not sure why the epub would be such a bad idea, as long as the creator realizes the limitations of ereaders. I threw together an example with 7 color photos formatted for a 6" grayscale reader and attached it to this post. The css was borrowed from other epubs and is more complex than you need but at least this will allow you to see what such an epub might look like (without any captions, etc. - only the 7 images on separate pages (and separate files), and how I handled the images. I used an jpg image size of 5" height and 200 dpi for each photo, and each image was scaled to fill 100% of the ereader screen width. It was checked on my bebook one. With a color ereader, of course, the images would look much much better. I hope this helps a bit.
