have you heat set the pictures? usually the paper peels off fairly easily once heated.- place a piece of muslin (or other scrap fabric down to catch any fugitive ink) place the picture face down on top of the pressing cloth- press with your iron on a cotton setting- peeling the paper from one corner- should come off.sometimes it is hard to get it started- try using the tip of a seam ripper- or a large pin to start the corner.
