I have several of my own photos that I need to add a simple watermark to; however, I would like to add stegonography to the watermarked layer in order to put the image information, the page that the image was to be placed on, etc... hidden within the watermarked layer. Is there a way that I can use php to view the stegonography data from the watermarked layer of the completed photo? If so, how?
