I dunno if this will work for you but if you open your picture in paint you can go to image and then to sketch/screw you can reduce the size of the pictures but changing the percentages and then saving it again as a new filename (just incase you mess up). Thought this might help its how I do my pictures.
Your babies are cute, I have to do the same thing soon I am getting Porscha a brother and I need to introduce them soon
