To do so, you can use the event handler oncontextmenu="return false;" within the IMG tag that defines your image:</p> <p><code>&lt;IMG border=0 src=&quot;...&quot; oncontextmenu=&quot;return false;&quot;&gt;</code></p> <p>As for alt-printscreen you can try this but i don't think it works for IE7.</p> <pre><code>&lt;HEAD&gt; &lt;script language=&quot;javascript&quot;&gt; function clearData(){ window.clipboardData.setData(&#39;text&#39;,&#39;&#39;) } function ccd(){ if(clipboardData){ clipboardData.clearData(); } } setInterval(&quot;ccd();&quot;, 1000); &lt;/script&gt; &lt;/HEAD&gt; &lt;body ondragstart=&quot;return false;&quot; onselectstart=&quot;return false;&quot; oncontextmenu=&quot;return false;&quot; onload=&quot;clearData();&quot; onblur=&quot;clearData();&quot;&gt;</code></pre> <p>Basicly if anyone can see it, they can and will find a way to grab it. There are hundreds of different ways to get images, browser cache, image capture software.. even the snippet tool in vista. I wouldn't waste my time implementing any of the suggestions above, but rather digital signatures or watermarks.</p> <p>Have a read up on this<br /> <a href="http://en.wikipedia.org/wiki/Digital_watermarking" rel="nofollow">http://en.wikipedia.org/wiki/Digital_watermarking</a> </p> <p>Some companies like digimarc have services to track other sites using your images. </p> <p>good luck,<br /> Drew </p> http://designsadvice.com/forums/topic/blocking-images-from-being-removed-from-webage#post-193 Thu, 13 Dec 2007 09:32:16 +0000 rockstar 193@http://designsadvice.com/forums/ <p>Hi<br /> I work as the website designer for a graphics design studio<br /> in the past we have had some of our designs stolen from the site by people who have either used the right-click-save method or the alt-printscreen method<br /> I know there is a way to keep people from using the right-click-save method, as i have seen it on other pages</p> <p>I would like to know,<br /> a. how do you do that<br /> b. how, if you could, would you stop the alt-printscreen method<br /> and finally<br /> c. are there any other ways people might be able to steal my images, and if so, how would i stop them from doing so?</p> <p>thanks</p> <p>Sam Wilson<br /> FireHouse Graphix, WebDesigner </p>
