The short answer is: you can't. Once you put it on the web, everyone can see and thus copy (print screen for example) your images.

In the past there have been some thorough debates on this subject on these lists. Some say maybe you can do it (using read-only PDF for example) others say you can't.

I tend to stick with the second group. I have yet to see an implementation that really works, and also blocks methods like screen-scraping. IMO, if you need to protect it, don't put it on the (public) Internet.

Cheers,

Imar

such as right click option des-able, copy option des-able.

Like I said, I am in the group of people that don't believe in protecting content this way on the public Internet, so I haven't really tried to come up with a solution.

If you search on Google on this topic, there are tons of articles devoted to this subject:

http://www.google.com/search?hl=en&i...click+web+page

http://www.hostapproval.com/articles...ght_click.html

http://www.promoteartist.com/article...ght_click.html

Check out all the other pages Google finds for you. There may be a HowTo somewhere, although the author of that article may prevent you from actually reading or printing the article :)

Cheers,

Imar
