    There are several ways to discourage thievery of images posted on the net:

    I've been able to Watermark successfully in the GIMP but this one has me beat:

    My problem is that JPEG and PNG formats don't support layers, AFAIK..

    Looking for suggestions on how to actually accomplish the above rather than general suggestions on how to protect images.

    P.S. I use GIMP for layers work and that's the only app with layers I have ...

    Thanks,

    I just now opened an image in the GIMP, put a transparent layer on top, saved as a PNG, put it up onto my site, downloaded it and opened the download in FastStone.

    The download was perfectly visible and editable, so not protected by a "hidden layer".

    Hmmm ... I must be missing something, duh!

    The hidden layer they are referring to is not in the actual image.

    What they mean by 'hidden layer' is adding an image containing just transparent pixels on top of the actual image in the web pages html with CSS. Using the CSS z-index and position styles you place the transparent image as a layer (effectively a sheet of glass) directly on top of the image.

    That way when someone right-clicks the image on a web page and then "Save image" the browser downloads just the top layer, the transparent image and not the image itself underneath, onto the user's pc.

    It is physically impossible to stop anyone taking an image from a web page. At the very least they can take a screenshot of the image and then using any of the AI driven image enlarging apps upsize it to whatever is useable to them.
