<P>Hi Paul,</P>
<P>You are absolutely correct in what you are saying, I know it and the client knows it. The measures you suggest are already in place, and the client acknowledges the fact that you cannot stop a visitor taking your images. Watermarks are really the way to go, which the client is implementing.</P>

do this in order to <BR>>placate client fears, even when you know perfectly well it's <BR>>tissue-paper armor.<BR>><BR>>However, if you allow your client to feel safe and then someone <BR>>scrapes their work off their site, their disappointment might well <BR>>express as anger toward you for leaving loopholes in that tissue <BR>>armor. Some clients sue if they feel they've been misled and ripped <BR>>off. You might want to consider asking your client to sign a letter <BR>>stating that they understand that the image-saving blocks you're <BR>>adding to their site will not prevent a sophisticated user from <BR>>scraping the images.<BR>><BR>>The click-blocking techniques you're contemplating will discourage <BR>>only the most naive computer users. I imagine these are not the <BR>>people your client really has to
worry about. Anyone serious about <BR>>taking images from a web page can stroll around them. It's like <BR>>adding a reinforced door to a room without walls.<BR>><BR>>As you know, if I can see an image on the screen I can save it as a <BR>>screenshot; if an image appears on a web page then it's already been <BR>>downloaded to my cache; JavaScript is easy to turn off; the Firefox <BR>>web developer tool bar gives me access to all images on the page, as <BR>>well as to the JavaScript-generated page source; and so on.<BR>><BR>>My recommendation is that your client watermark the images on their <BR>>site -- which both displays a notice of ownership and effectively <BR>>ruins the photos for unauthorized re-use -- and then ENCOURAGE <BR>>people to save them, send them to friends, etc., in order to <BR>>increase awareness of their
work as much as possible.<BR>><BR>>Good luck,<BR>>Paul<BR>><BR>>_______________________________________________<BR>>Javascript mailing list<BR>>Javascript@LaTech.edu<BR>>https://lists.LaTech.edu/mailman/listinfo/javascript<BR></FONT></BLOCKQUOTE></div></html>
