Hack 58 Protect Your Copyright
Prevent other sellers from stealing yourphotos.Taking
a good-quality photo of each and every item being sold can be
extraordinarily time consuming, not to mention practically impossible
for items still in their boxes or not in the
seller's immediate possession. As a result, many
sellers resort to hijacking other sellers' photos
for use in their own auctions.The problem is that photo theft can be extremely damaging, and not so
much because of mere copyright law (although it does apply).A big part of any auction's desirability is its
uniqueness. The more uncommon an item appears to bidders, the more
valuable it becomes. When bidders see the same exact photo in two
different auctions, not only are the implied scarcity and value of
the item severely weakened, but the integrity of both sellers becomes
suspect. And unless it's painfully obvious, most
bidders won't distinguish between the thief and the
seller whose photos were pilfered; a single theft of an image will
hurt both sellers.
5.5.1 Protecting Your Image
My inspiration for this solution was a hot-dog vendor in my college
town. On a shelf next to the broiler sat an old black-and-white
television set, with the words "Stolen from Top
Dog" written in permanent marker on its side.The idea is to mark your photos so that they're
unusable by other sellers, but in a way that doesn't
adversely affect your own auctions. This is accomplished quite simply
with a bit of text superimposed right on your photos.The text should be carefully placed so that it
doesn't obscure the subject but also
can't be easily removed by the thief (such as with
the clone tool in [Hack #57]). Often
the easiest way to do this is with large, translucent text right over
the center of the image, as in Figure 5-7.
Figure 5-7. Tagging your photos with your eBay user ID is an effective deterrent against image theft
The specific text you use is up to you, but it should include a
copyright symbol (©) and your eBay user ID. The user ID is
important, as it indicates that the photo belongs in your auction and
no one else's.
5.5.2 Disable Right-Click
The
right mouse button is what most people use if they want to save an
image on a web page. If you want to take an aggressive stance on
image theft, you can disable your customers' right
mouse buttons for your auction photos. Just include this code
somewhere in your auction description:[1][1] Based on code
snippets by Martin Webb (www.irt.org).
<script language="JavaScript1.1"><!--
function lockout( ) {
for (var i=0; i < document.images.length; i++) {
document.images[i].onmousedown = norightclick; [1]
document.images[i].oncontextmenu = nocontextmenu; [2]
}
}
function norightclick(mousebutton) {
if (navigator.appName == 'Netscape' &&
(mousebutton.which == 3 || mousebutton.which == 2)) {
alert("Please don't steal my pix."); [3]
return false;
}
}
function nocontextmenu( ) {
event.cancelBubble = true; [4]
event.returnValue = false;
return false;
}
if (document.layers) { [5]
window.captureevents(event.mousedown);
window.onmousedown=norightclick;
}
// --></script>
<body onLoad="lockout( );"> [6]
Here's how it works. The
lockout function sets two rules for the
page: any time a user clicks an image on the page, the
norightclick function is run [1], and any time a user opens a context menu on
an image, the nocontextmenu function is run [2]. Later on, the <body>
tag [6] calls the lockout
function only when the page has completely loaded, otherwise, the
for loop would miss any images that
haven't yet finished loading.The norightclick function then blocks the right
click with a warning message [3], but only
for Netscape and Mozilla browsers. The
nocontextmenu function disables the context menu
with no warning [4], but only for Internet
Explorer. The two browsers are handled differently because only
Internet Explorer supports the oncontextmenu
event. (And, to cover all our bases, there's a bit
of code to handle older versions of Netscape [5].)This code is by no means foolproof. Any knowledgeable or determined
user can disable JavaScript, or view the page source, or perform a
screen capture, or simply drag-and-drop images off the page (for
browsers that support it). But most users who steal images do so
because they don't know any better, and this script
gets the point across.
5.5.3 Other Ways to Protect Your Copyright
Here are a few other ways to protect your images from being stolen:If you're hosting your own photos, take them down
right after your auctions close to reduce the window during which
other sellers might find and steal your images. But this could arouse
the suspicions of your winning bidder, and would weaken the marketing
power of any photos in your completed auctions that might otherwise
help drive bidders to your current items.If you're really concerned about image copyright,
you can use CopySafe Pro (available at www.artistscope.com), a Java-enabled image
viewer. It may be overkill for simple auction photos and
it's not foolproof, but it may be the additional
security you're looking for.Some image editors, like Photoshop, support invisible watermarking, a
method by which images can be marked and later identified for
copyright infringement. Image thieves won't ever
know it's there, but it can be useful for proving
that theft has taken place.
5.5.4 Reporting Image Thieves
The most effective means of
protecting your images is to simply report any auctions in which
another seller has used one of your images without permission.

the Rules & Safety Support page, select Questionable Content on
eBay
Potentially Infringing Issues Use ofImages, Text or Links without Proper Permission. Click Continue and
then click Contact Support on the next page. Finally, specify the
offending item number(s) in the first box and explain the offense in
the second box. Be sure to include the item number of your original
auction in the second box to show that it was you who posted the
image first.eBay typically takes 2-3 days to investigate and respond to claims.
In the case of content theft, eBay will simply remove the offending
auction and explain the situation to the seller (assuming
you've sufficiently proven your case).
