Here are some ideas if you want to make it a little bit more difficult for others to save your pictures:


1. Get rid of the new Graphic Menu feature of MSIE
(i.e. the little menu with the Save icon that appears in IE 6 as soon as you move your mouse over an image)

Copy this line into the section of your page:



----------------------------------------------------


2. Disable the Right Click Menu

Disabling this menu is considered bad style but is very effective. The following script works for NS4-6 and IE4-6. I wrote it myself, use it if you like it ...

Copy the following lines (including the <script> tags into the section of your page:


<script language="JavaScript1.1">



---------------------------------------------------

3. Make them save a fake picture

This is my personal favorite. Simply place a transparent gif above the original picture. Give your fake a promising name and nobody will realize that he saved an empty image ;D

What you need is a small transparent gif, named something promising like pic17.gif

Copy the following line between the end of the head and the beginning of the body section of your webpage.
It defines a general purpose area that is positioned above everything else on your webpage (z-index=999). Adjust the values for top and left, if you want your protection to start somewhere lower or to the right.


between



and


Copy the following line before the end of your body section.
It fills the area (named picsaver) previously defined with the transparent gif image (named pic17.gif).
If the image is in another directory than your page, you have to add the path (something like "../images/pic17.gif".
If the area to hide is smaller or larger you have to adjust the height and width values.



before


If you're using this example, the right click menu will offer to save pic17.gif. Make sure that the top and left positions (of #picsaver) and the image width and height match your webpage.

Demos can be found in my galleries, try one of these

Have fun - Sabine

I tend to use the right-click to open image links in a new window (to avoid a slow re-navigate back to an index page) and I find the right-click interceptors really annoying. Especially since if I really wanted to steal the images it would be easy regardless of the above steps!

The invisible gif trick is quite clever!

However I'm sure you're aware it would be pretty trivial to write a tool to circumvent all the above steps if someone was determined. A more tamperproof solution might be to use something like Flash to host your slide show/image gallery -- that would stop `em! Though of course it's much more heavyweight and requires the viewer install a plugin at some point. Plus you'd have to buy the authoring toolkit.

Thanks for the post, it's educational!
