big challenge for all you webmasters out there

[Weapon]

I have two script on my page one is a image script so I don't have to make a page for every image and the second one is a anti leech script for the image

anti leech: http://yoursite.com/cgi-bin/downloader.cgi?site=1&filename=thefile.zip
image: http://yoursite.net/cgi-bin/image.pl?directoryofimage/the file.jpg

so how would I put the two script together so they can't steal my images but are still able to view them from the original site?

[Canuckkev]

Hmm, copy and paste the codes into the same script, then it should be able to show the image and make it anti-leechable. A bit of editing could fix it. If you give me your code, I could probably help.

The anti-leech:


#!/usr/bin/perl

$defaulturl = "http://cgi-scripting.com";

@okaysites = ("http://cgi-scripting.com", "http://www.cgi-scripting.com");

$url_1 = "http://yahoo.com";
$url_2 = "http://downloads.com";
$url_3 = "http://downloads.com/new";


@querypairs = split(/&/, $ENV{'QUERY_STRING'});
foreach $querypair (@querypairs) {
($queryname, $queryvalue) = split(/=/, $querypair);
$queryvalue =~ tr/+/ /;
$queryvalue =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;
$queryvalue =~ s/<([^>]|\n)*>//g;
if ($QUERY{$queryname}) { $QUERY{$queryname} = $QUERY{$queryname}.",".$queryvalue; }
else { $QUERY{$queryname} = $queryvalue; }
}

$reffer = $ENV{'HTTP_REFERER'};
$yes = 0;
foreach $domain (@okaysites) {
if ($reffer =~ /$domain/) {
$yes = 1;
}
}


if ($url_$QUERY{'site'} && $yes == 1) {
print "Location: $url_$QUERY{'site'}/$QUERY{'filename'}\n\n";
} else {
print "Location: $defaulturl\n\n";
}
exit;


The image script:

#!/usr/local/bin/perl

$headfile = '/data1/hypermart.net/otashki/header.txt';

$footfile = '/data1/hypermart.net/otashki/footer.txt';

$File = $ENV{'QUERY_STRING'};


unless (open (DATA,"$headfile")) {die (&error);}
if ($uselock eq '1') {
flock DATA, 2;
seek DATA, 0, 0;
}
@headinfo = <DATA>;
if ($uselock eq '1') {
flock DATA, 8;
}
close (DATA);
foreach $headline (@headinfo){
$heading = $heading.$headline;
}


unless (open (DATA,"$footfile")) {die (&error);}
if ($uselock eq '1') {
flock DATA, 2;
seek DATA, 0, 0;
}
@footinfo = <DATA>;
if ($uselock eq '1') {
flock DATA, 8;
}
close (DATA);
foreach $footline (@footinfo){
$footer = $footer.$footline;
}


print "Content-type:text/html\n\n";
print "$heading";
print "<CENTER><IMG SRC=\"$File\"></CENTER>";
print "$footer";

so with anti-leech you merely mean they can't link to it from your site... Cool :)

(sorry can't help though)

[Canuckkev]

Just before I spend some time on this, let me clarify things. You want your .jpg's to be protected by the antileech, right? And the jpg's will show up on the cgi generated page, right? Just making sure I understand, cause if that is the case, in the line :

print "<CENTER><IMG SRC=\"$File\"></CENTER>";


You could replace it with

print "<CENTER><IMG SRC=\"http://yoursite.com/cgi-bin/downloader.cgi?site=1&filename=$File\"></CENTER>";

Might still need to be fixed up a bit, depending on where the directory is or stuff like that.

Oh, and by the way, that's the same image gallery script that I edited up to suit my own needs. :)

But if I do it that way I can link the images to multiple directory

[Canuckkev]

Huh? Do you mean "Can I link the images to multiple directory?" I think so. If your ?query string is a http:// address, this will be possible. Otherwise you would have to add more scripting to receive variables from the ?query like ?file=pic.jpg&dir=pics. It would be easy if your anti-leech script was in the base directory, otherwise each ?query must be like
?http://mydomain.com/dir/file.jpg

[Weapon]

do you know any other script that would save my images from being linked/stolen?

[atlas]

Just edit your main script to check the referrer to make sure it's an accepted site. Either that or I'm not understanding what you wish to do.

-mk

[Canuckkev]

Yeah, the easiest would be to check your refferer in the image script. Just use this script, and all should be good:

#!/usr/local/bin/perl

@okaysites = ("http://cgi-scripting.com", "http://www.cgi-scripting.com");

$reffer = $ENV{'HTTP_REFERER'};

$headfile = '/data1/hypermart.net/otashki/header.txt';

$footfile = '/data1/hypermart.net/otashki/footer.txt';

$File = $ENV{'QUERY_STRING'};


unless (open (DATA,"$headfile")) {die (&error);}
if ($uselock eq '1') {
flock DATA, 2;
seek DATA, 0, 0;
}
@headinfo = <DATA>;
if ($uselock eq '1') {
flock DATA, 8;
}
close (DATA);
foreach $headline (@headinfo){
$heading = $heading.$headline;
}

unless (open (DATA,"$footfile")) {die (&error);}
if ($uselock eq '1') {
flock DATA, 2;
seek DATA, 0, 0;
}
@footinfo = <DATA>;
if ($uselock eq '1') {
flock DATA, 8;
}
close (DATA);
foreach $footline (@footinfo){
$footer = $footer.$footline;
}


foreach $domain (@okaysites) {
if ($reffer =~ /$domain/) {

print "Content-type:text/html\n\n";
print "$heading";
print "<CENTER><IMG SRC=\"$File\"></CENTER>";
print "$footer";
exit;
}
}
sub error {
print "Content-type:text/html\n\n";
print "Error!";
exit;
}

Did it work? Did it work? ;)

[Weapon]

yeah it works, but I was thinking if they right click on the image after they click the link and the image loads will they still be able to go "copy image location..." then put it on their page?

How about a thankyou, to those that helped? ;)

If they can see it they can steal it.

You can only stop them linking to your image rather than putting a copy of it on their site

[}:8) Supermoo]

Although you could try an onMouseOver & onButtonDown watermark. Which would stop many thefts.

Also, try encryting the HTML code and no-one should be able to find it! :)

Although don't over use this as it will most likley triple loading times, but if you need it... it will work. ;)

[Canuckkev]

Oh, I thought you wanted it to be unable to be linked from your site. Now you want it so they can't copy it? Well, put up a copyright statement...it may stop one or two people. If someone wants to copy it, they will be able to break any code you put in to make it uncopyable(sp?) Or, a real desperate person may take a screen shot.

Oh, and glad it works. I can never seem to get anything of my own to work.

[Weapon]

no this is just to stop bandwidth theft so would it? I don't want to pay for more bandwidth you know

[Canuckkev]

Well, it should stop bandwidth theft. Don;t see how it couldn't.

Can't they go right click in the image then properties then copy the url?

[gyrbo]

That's the good of the script! You need to link from a site under his server!

What are you trying to say here? What I am trying to say is that I will have to pay for more bandwidth. Also anyone know the script to disable right click but instead of popping up a message it says nothing? and how do you link a .js file to your page like a style sheet?

[Edited by Weapon on 04-06-2001 at 06:13 AM]

Just like a stylesheet?
<LINK REL="Something" TYPE="text/js" HREF="file.js">?

[Weapon]

well I managed to link the seperate .js file to my site but I was just wondering how do you put two script into one .js file? do you put a - or some sort to tell where one script ends and the other start?

[lucifer]

just put the second one after the first

maybe add a

// this is where the next script starts

comment for later reference
