This is the problem I am encountering now.
Watermarks are good but I really do not want to distort my images.
Someone once told me to make my pages into a JPEG and then post it...problem is the file would be too large.
And I cannot depend on the courtesy and tact of others to E-Mail me about it.....but it would be cool if a web program was made that let you control what aspects of your site can be copied and what ones cannot.
But the Internet is really still in its infancy...it is still a relatively new technology so I can only hope new codings and such will be put in place.
