I am trying to help a friend who is an artist with her website. She would
like to make sure no one can print or copy her pictures of her paintings. How
would I go about doing this?
When the picture can be seen on the visitor's monitor, the file is in
that visitor's computer and can be printed. All you can do is make it
more difficult to print the picture and make the result less
attractive visually.
Here are some option that can also be used in combination:
1) disable right click (will only deter newbies, and upset everyone)
2) use low resolution image (72 dpi is good for screen , but low for
printing)
3) use image with copyright notice written (embossed) across it
4) slice image and place slices in table (a person would have to save
a slice at the time and reassemble the table)
5) do as in 4, but use slices as cell backgrounds and place a clear
gif over them (right-click save will get a lot a of clear gifs, though
the slices are still in the cache)
6) change image into flash file (swf), password protect.
etc.
Place malicious content on web site that will crash visitor's computer
(just joking of course)
I photographer friend had the same concerns as your friend. When we
discussed it, it turned out that one concern was about losing an
actual sale because of a potential client printing an image off the
net rather than making a purchase. The other concern was about
unscrupulous companies selling her work. The concern of somebody, who
would NOT purchase the photograph in the first place, using a low
resolution picture, with copyright embossed into it was much less of a
concern.
