Thanks alot. Re-reviewing the URLs revealed that they were missing the integral "i." and ".jpg" in them. I was apparently copying the wrong URLs for direct image linking. And I do intend on sticking this through. And going so far as to complete a full set of armor, funding allowing.
I have started and stopped on various projects since I learned of pepakura. Often getting frustrated because of what a mess it was. But now, with encouragment from my wonderful girlfriend, I have knuckled down and am sticking it out. I've never done anything like this before so I expect results...
