How do I 'lock up' graphics?
I am working on a new website and would like to know how I can go about locking up a copywritten jpg. & gif. files so that no one can "right click and save as"?
Is there a simple html code? or would a java ap work?
Thanks!!

i believe the only way to do this is to display the image through a java applet. there are some tricks you can use, such as disabling the right mouse button over images and forcing the page into a frameset so the source isnt easy to get at, but anyone with a little knowledge can get around that. even if you did find out an effective way anyone can just take a screenshot into photoshop and crop it.

Yup, there is a code in javascript that allows you to "disable the right click" on the mouse so the visitor can't view your html doc.

Look for "No-Right-Click"

The javascript code is pretty easy to defeat. You can just save the picture out of your cache or use Netscape, in which the javascript doesn't work. It is also real easy to strip the frame and get the picture there.
The main problem with pictures is that the browser must be able to read them making virtually any technique defeatable. The other problem is that if you try to lock down the pictures, it will only make someone more determined to get to them. I saw one site that use a bit of java code on it's site. When you right-clicked and saved the picture, it changed the resolution to 1 pixel per inch. So a 200x200 pixel picture became 200 inches X 200 inches, making it impossible to edit and print. This could be defeated by saving the image as a bmp and then converting to a jpg. I liked this technique because it was a bit stealthy and the person may forget where he got the picture from.
Another thing to experiment with is to try altering the picture. This works if it is a piece of artwork. You could add a text layer over the picture that says copyright. Make the text big enough to make it hard to edit out. Place it in an area that can't be edited easily.
Hope this helps.

I dislike those "no right click" scripts. If someone really wants to get it, they can - and will. It's just more of an annoyance than anything to me, IMO.

Yes, they're easy to get past. It is extremely annoying if you're using image links, because especially in frame sites people use the right-click button to activate links and other things besides grabbing pictures. It makes the site less user-friendly, WAY less user friendly.

I agree, the right click scripts are fairly ineffective. First, you should ask yourself if your graphics are really so good that someone else is going to want to steal them. If so, why not consider a watermark? I also remember seeing something a while ago that displayed your image as a java applet, I'll let you know if I find the URL.

I think like a bit like Brian. It's not worth the trouble unless it's something you'll be selling.
Both these were mentioned earlier:
Corbis Images puts there name accross the whole thing. Or you can watermark the images (an invisible copywrite thingy). Both don't prevent people from stealing the images, but both make it harder to use.

So how do they do it on terraserver.com
You cannot save the pictures from there. And you cannot screen capture them with a program like paint shop pro.
If you CAN capture these images, I would love to know how.
Thanks

I'm sorry, they changed the site. It appears that you can save the images now.
But previously they had some plug-in that was required to view the pictures. I can't remembere the name right now.
the pictures are here

then you drill down to the area you want and pick aerial photos

I would also like to point out that "no right click" scripts have no effect on a Mac.
