By saying that you have the original pictures, I assume you mean the digital images that were used to create this quilt. I would send those off to a professional place that prints images on fabric. They use printers and ink that result in longer lasting pictures. I would then take the quilt top apart, remove the picture fabrics, and replace them with the new ones, put the quilt back together just like it was when new, but quilt it and sew on a real binding. That should give him essentially the same quilt as before, but with images that will last much longer. And it wouldn't be that difficult for you.
