Steganography has been able to "hide" text in images for quite some time now. Basically you cram whatever info you want into the 'unused' or 'less used' bytes of the image. With this in mind I imagine even if you did have an image repository of only 8 images you could add some random bytes to the right spots in the image without distorting it beyond recognition/corrupting it, and therefore get a hybrid of static/on-the-fly images, that hashing couldn't break so simply.Yes, that's the conclusion I came to in this experiment.
