>It sure sounds like there is a limit, but I don't know anything more about it.

It is really weird. Like, right now, in order to generate the entire magazine, I have put a condition not to include images that are over 50k. So, I get all the pages but half of the images are missing. I have been looking at the XML and tried to find if there could be a limit. I did a lot of searches tonight on the net and also couldn't find anything.
