How to protect HTML content?.

hellothis is what I was looking for, at least I imagine I would like to eliminate the tiny image that pops up whenever you put the mouse cursor over an image (the toolbar image? save, print etc ... ) I followed your instructions adding the metadata to the image itself and I published the course (to html) to test the trick but it did not work ....by the way I'm publishing for test purpose, it will be published on line to AICC ... any further suggestion please ?

Thanks a lot Phil, this is clear and very helpful.Best regards and a great (Lectora) 2005,Sjaak.

Another approach, similar to disaacks is to chop your image up into two, three, or 4 chunks. To grab your image they would have to grab all 4. The first time they would be fooled. The second time it would just be tedious so they might move on.Of course, the easiest way to thwart all of this is to do an ALT-PrintScrn on the window with the image, then paste it into a graphics program like Paintshop Pro or Photoshop. Then they have the image regardless of the means you attempt to stop them. In actuality any of these techniques barely slows down someone who is intent on grabbing your stuff.

Thanks a lot David - very helpful indeed! Regards,Sjaak.

Disabling Right Click Saving of your Images without JavaYou can also use another a simple non-Java method to prevent right click saving of your images. This involves fooling the user into thinking they are saving your image, but in fact they are only saving a transparent empty gif. Here's a demo I made to illustrate how it works. Try saving the image at the URL below by right clicking and choosing Save Picture As.http://www.angelfire.com/on3/vxdoin2/bugsy.htmAs you can see when you view your saved file, all you end up saving is a transparent gif. The image is actually the background for a table cell and the transparent gif is covering it. It's a simple technique. Create a transparent gif and place it together with your image file.Here's the demo code:

Bugzy.gif is the transparent gif which the user ends up saving. Almost any graphics program will let you create a transparent gif, easily. I use Photo Editor. I set the size to a small 10X10 pixels and then just click Tools/Set Transparent Colors.This method isn't as effective as the Java method, since it makes it much easier for a user to get your images by saving as complete web page. With the Java method, the right click would still be disabled when saving the page. The user would still have to know how to edit the source code.

Sjaak,I use two External HTML objects in the title. The first one I call NoShow_Imagetoolbar, prevents the image toolbar from showing when the cursor is placed over it. The custom HTML is:.The second object is called No_Right_Click and prevents a users from right clicking on your images. The custom HTML is:var msg="Your right click option has been disabled to protect our media.";function click(e) {if (document.all) {if (event.button == 2) {alert(msg);return false;}}if (document.layers) {if (e.which == 3) {alert(msg);return false;}}}if (document.layers) {document.captureEvents(Event.MOUSEDOWN);}document.onmousedown=click;Although it will not prevent someone from grabbing your stuff if they really want it, it will slow down many of the users.Hope this is helpful.Phil
