Disable right click for images only - 6/12/2002 11:00:21
I haven't personally used this, but ran across it while looking for a script for something else. Looks pretty neat, you can disable right click for images only, so you don't prevent users from using right click for other functions. It displays a message that says "Right click disable on images!". I assume you could change that to say the image is copyright-protected, or whatever you want.

If you take an image an slice it 10,000 times.. naming each clice differently.. that oughta stop someone from stealing the image and if they did capture all slices then they deserve it.

Good point, Kim
And Jman - that's the best solution I've heard yet!!! I wonder how long that would take to load in a page..?

except it doesn' t prevent people from taking a screenshot! (then cropping the image and using it)

Here is a solution I use that seems to work out for me.
Create a file called " getimage.asp" and put the following code into it.
<%
' Get where the request came from
Dim strBuffer, File
PathstrBuffer = Request.ServerVariables(" HTTP_REFERER" )
' Specify the path we should be served from
' (This can be another web site (http://www.site2.com) or
' some directory where the web surfer will not expect to
' find your images...
FilePath = " /ProtectedImages/"
' Test to see if we should serve the file or not
if Instr( strBuffer, " mydomain.com" ) <> 0 then
' The Image can be served
FilePath = FilePath + Request.QueryString(" FName" )
Else
' They are trying to leach our file!!
FilePath = " /images/leacher.gif"
End If
' Send them to the appropriate file
Response.Redirect(FilePath)
%>
Now, in your page you reference your protected image like so:
<img border=" 0" SRC=" /aotw/images/getimage.asp?FName=wwr_250.gif" >

Here is the thread that my above code was originally placed and some other options were thrown in.

I think Dave' s point remains valid though - you can do whatever you like, serve it up any which way, but you cannot stop someone cropping a screen capture, no way, no how.
Taking a screen capture can hardly count as a high tech method likely to be known only to the very savvy. I reckon that there is not a living person of the sort who would be given to stealing images who would not know how to do that.
Even watermarking will do you no good there - unless it is in the form of a great big lump of text accross the image which renders taking it pointless.
There are certain situations where that works - eg where a thumbnail is available, and if anyone wants the skittery little thing let them have it, but the larger image is defaced in this way. Lots of sites selling images use this method. It does not prevent people taking the images but it does make them pretty useless.

My issue wasnt the stealing of images as much as it was people liking my 9-11 graphic and linking directly to it from thier own site... I was getting my bandwidth chewed up like a cow bathing in a sea of pirahna... Just needed a quick way to discourage direct linking.
Otherwise I agree with the argument... if they want it bad enough, they' ll find a way.

If someone wants the image they can simply take a screenshot and crop it out. Why go through the trouble of putting in code to prevent right click?
:)

You are right - people calling your images from your server is totally not acceptable but there are a number of ways around it, one is yours.
If you are on a Unix server you can prevent linking to images using your .htaccess file - more here:

Katherine:
I followed your .htaccess article and made up the following (added to an existing file which only had ' Options ExecCGI' in it):
<Files .htaccess>
order allow,deny
deny from all
</Files>
Options ExecCGI
RewriteCond %{HTTP_USER_AGENT} Wget [OR]
RewriteCond %{HTTP_USER_AGENT} CherryPickerSE [OR]
RewriteCond %{HTTP_USER_AGENT} CherryPickerElite [OR]
RewriteCond %{HTTP_USER_AGENT} EmailCollector [OR]
RewriteCond %{HTTP_USER_AGENT} EmailSiphon [OR]
RewriteCond %{HTTP_USER_AGENT} EmailWolf [OR]
RewriteCond %{HTTP_USER_AGENT} ExtractorPro
RewriteRule ^.*$ X.html [L]
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?searoom.com/.*$ [NC]
RewriteRule \.(gif|jpg)$ - [F]
RewriteRule \.(gif|jpg)$ http://www.searoom.com/images/stealing.gif [R,L]
The result is that the browser is refused access to the site! Any comments?

who cares! you cant prevent images or else info copying.
if there are no right clicks people just can take a snap and just edit tha picture in graphic editing program.

. It amazes me how people can get offended because someone does something on their web site. It' s probably not the best choice for protection but it is their web site to do anything they want.
