LANGUAGE="JavaScript">document.referrer.indexOf("http://www.example.com")
!= -1){ document.write("http://www.example.com/image1.jpg")} </SCRIPT>

or how to property set document.referrer, would something like this work:

<SCRIPT LANGUAGE="JavaScript">
{
document.referrer == 'http://www.example.com;
document.write('<img src=http://www.example.com/image1.jpg width="60"
height="60">');

}
</SCRIPT>

You forgot the closing apostrophe of the string:

document.referrer == 'http://www.example.com';

Are you sure document.referrer would not return:
'http://www.example.com/'
or
'http://www.example.com/index.html'
etc?

Or do you want to test true for any referrer from that domain?

The double '==' compares the two strings, but you do not use the result.

Do you mean:

if (document.referrer == 'http://www.example.com')
document.write('...

??


> document.write('<img src=http://www.example.com/image1.jpg width="60"
> height="60">');

I would enclose the URL string in quotes
scr="http://www.example.com/image1.jpg"

> width="60"
> height="60"

Use css styles:

style='width:60px;height:60px'


>
>}

no need for that }

> </SCRIPT>

===============

I would suggest the following:

<script type='text/javascript'>

var url = 'http://www.example.com';
var s = "<img src='"+url+"/image1.jpg'";
s += " style='width:60px;height:60px'>";

if (document.referrer.substr(0,url.length) == url)
document.write(s);

</script>

not tested

Did you test it? You didn't or you wouldn't be asking that question.

The language attribute is deprecated, use type instead:

<script type = "text/javascript">

>From what I gather, you're saying if I didn't come from the example
site, then you're gonna take and use their content. I would say that's
the only thing wrong with your code. And it's not foolproof, meaning I
could come from different site, and there would be no way that you
could cover all the cases. I don't even have to come from a site. I
can just launch an empty window, and navigate to your site. In which
case, document.referrer would be empty.
