You nead to set Anchor to your pictures

for (int i = 1; i <= 2; i++) {
    byte[] pictureData = IOUtils.toByteArray(new FileInputStream(
            "C:\\Users\\Ashok\\Pictures\\" + i + ".png"));
    int elementIndex = ppt.addPicture(pictureData,
            XSLFPictureData.PICTURE_TYPE_PNG);
    XSLFPictureShape picture = slide.createPicture(elementIndex);

    // Set picture position and size
    picture.setAnchor(new Rectangle(positionX, positionY, width, height));

    List<XSLFPictureData> allPictures = ppt.getAllPictures();
    System.out.println(allPictures.size());
