You can make the life for sucker harder, but if they want,
they get the Images... (e.g. browser cache).
The only thing is to use "Watermarks" (expensive because the license).
I dont have direct <IMG src=""image.jpg"> links... I do it with
php4 and try to hide the originating path. And second I change
the location/nummeric association all two hours.
Forget to change the $_SERVER['HTTP_REFERER'] and something like this,
it can be forged by 'wget' and friends (I have tried it my self).
YES, I TRY TO HACK MY OWN WEBSITE !!! grrr...
And third if someone try to download more the one PIC in a specified
time, my friend php will blocked the IP...

Right, but in the same time reduce the quality
to a minimum or use progresive JPEG :-)
Question: Do you have a IMAGE-Spliter ?
I was looking for a tol which
can do it, but have not found.

This is probably the best way, but instead of static chunks you should
use dynamic ones with gd or something. It is still relatively easy to
get the image though. The other problem with this is that it basically
ruins all sense of accessibility.

Another thing - one way to stop them from doing "save image as" or getting
files from the cache is to split the image into a number of squares and
display all of them. If someone tries to save an image they will then either
have to save all the pieces and put them together like a jigsaw, or do a
screen capture. Not perfect but makes most people "not be bothered" =-)
