Just a thought, try to keep the size of the image between 480x622 (and scaled down proportionately to preserve your image's aspect ratio).
In your case try an image size of 430x622 and see it that makes a difference.
If that doesn't work, try 415x600 and increase the image size until you get the blank page again. Then that's your max. image size!
