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