    Post Prevent copying Pictures in Win7

    Hi all, thanks for letting me join.

    This might not be in the right place. But I am looking for ideas on scripting a no copy function in Windows 7. I have made some wallpapers for the works machine, and I need to stop others copying them and claiming they did them.

    I have seen it done in HTML and Javascript on web sites, it also issues a copyright warning.

    Can anybody suggest where to look or start please?

    regards
    Geoff

    Looks like the wrong word (even when spelled correctly).

    I think he means that the user should hide a message somewhere in the wallpaper which says he made it

    Ahh, but that's called watermarking.

    @ dillettante,

    According to that wakipedia that article you liked to says:

    Quote Originally Posted by the article

In either case, as in visible watermarking, the objective is to attach ownership or other descriptive information to the signal in a way that is difficult to remove. It also is possible to use hidden embedded information as a means of covert communication between individuals.
    I put the important part in bold. Which, suggests HanneSThEGreaT was correct. Although, wakipedia is known for having some incorrect info.

    The article is saying an invisible watermark may be a form of steganography. It is not saying or implying that the words mean the same thing.

    If you go looking for a feature to accomplish this in image processing tools you look for watermarking.

    I don't know if this may interest you, but you can also create an invisible watermark by writing on the image file at the end, using the "append" method.

    But none of this prevents copying anyway.

    And either the OP was a drive-by membership we'll never see post again or he's waiting for some miraculous suggestion instead.
