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?

Loads of other hits on Google too - too many to list.
Jump to PostOK, I'm assuming that you're talking about creating a png file right? With a watermark layer containing steg info. You can combine layers dynamically with the GD library. The link I quoted should allow the info to be written and read via php Am I missing the point here?

Jump to PostLol. DarkBerzerk, what a child you truly are.
wrstrong, please find another example of this, including a demo at the following link.

Jump to PostThe third party links on the above site are worth a look. The class I offered is also worth investigating.
I will distance myself from the "good-natured banter" and wish you good luck.

Neither option is secure, as the user can just view page source and browse directly to image URL.
