    HI

    Table Background & Transparent GIF are the new trend to protect your
    pics. Is it efficient or can people still go around and take my pics?

    thanks

    Define 'efficient'. *Sufficient*, no.

    > or can people still go around and take my pics?


    Yes. If it can be viewed in a browser, it has already been
    downloaded and is already taken.

    Ick! Why a table? Just use an image element:

    <img src="transImg.png" width="130" height="120"
    style="background-image:url(realImg.png);">

    But, as you can see, the URL of the real image is still in the code.
    It has to be for the browser to be able to load and show it. You
    can hide it further away from the actual image element, but it must
    be there.

    There is *no* effective way to prevent people from saving images that
    they can see.

    You can obscure it more or less, to make it harder, but you should
    always consider whether the people that are so easily fooled are
    really the ones you need to protect yourself against ... and whether
    the extra work for you is really worth it.

    (The best attempt I have seen so far, is really an embedded windows
    media file which shows the image (a one frame movie) as an overlay
    .... fooling most screen capture programs, but not all. Still, it's not
    absolutely safe, and it makes too many assumptions about the receiver
    for internet use)

    If you want to protect your pictures - really protect - the only way is not
    to show them in the web at all. If this is not an option, then there is no
    way in hell you could prevent people from saving it. It's only a matter of
    the degree how difficult you can make it, but there's always a way, if you
    choose to display them. What do you think would prevent the person from
    taking a screenshot, opening it in an image editor, cropping the image and
    saving it?

    but the so-called "protection" you mentioned might actually stop the dumbest
    most idiotic people on the web, which that makes about 95% of all people on
    the web. Still there's the 5% smarter than the average bear, who will find a
    way. If it helps you sleep in the night and creates the comforting false
    sense of security, feel free to use it.
