I downloaded a 300 dpi 1600 by 1280 image off the internet then saved it as a 300 dpi image in sizes 256 by 256, 512 by 512 and 1024 by 1024 and here are the resulting armor images. I can not see any real difference maybe you can.

I always save my armor images at a minimum of 300 dpi [dots per inch] regardless of the actual size of the canvas so to speak.
Now I have also done several single color armors and some using high definition images of real chain mail and my eye can not detect a difference based on image size only when the dots per inch are changed. Now normally programs like photoshop and its clones save images be they gif, jpeg, png, psd or whatever at 72 dpi. So when making things at whatever resolution for a game I make sure to save at 300 or higher dpi and for photos I save them at the native dpi even when I reduce the size of the image. One extra step but it does help the looks of things.
