Steganography methods have been proposed for embedding a single photographic image (image B) into another single photographic image (image A). Image A' is generated by integrating information from image B into image A, and then image B' is reconstructed by extracting the embedded information from image A'. The conventional methods are limited to embedding one photographic image into another. Therefore, we extend the conventional approach and propose a technique for embedding multiple photographic images into a single photographic image. In the proposed method, as more images B are incorporated into image A, the image quality of image A' deteriorates, while the image quality of images B' remains unaffected. To validate the effectiveness of the proposed method, experiments were conducted using various photographic images. The results of these experiments elucidate the relationship between the number of images B and the resulting image quality of image A'.
