At lot of it has to do with the format of the image (size, resolution, number of colors). If it's close to the native resolution/greyscale on the DR then it's fairly simple for the device to display it. If it's way off then the DR needs to essentially re-render the image before it will display. That's what makes some images take longer than others to open. On the iLiad (and I assume similar on the DR), if an image is really large then it's possible for the device to run out of memory while it's trying to re-render it and exit out of the PDF viewer (aka "crash").

I don't know what other devices are doing that allows them to handle large images. Perhaps they are using a different algorithm for resizing the images that takes less overhead but possibly doesn't look as good?
