Actually, TIFF files are better quality, but it's not that big a deal. Just remember that even with the Bubble Set stuff, the quilt really isn't washable more than once or twice (if that) without losing the photos. For a truly permanent photo, that will survive normal washings, you will need to have the photos printed professionally (on the fabric of your choice, of course). Ask me how I know!! This quilt has been washed in a regular washer more than a dozen times. The photos are still perfect.
