Re: $ENV{'HTTP_REFERRER'} and images

A couple things.

All information the browser sends you is potentially suspect, so keep that in mind.
HTTP_REFERRER for an <img> is the page on which the <img> tag sits. No amount of wishing is going to alter that.
Your best bet is to embed in the img src, a query string parameter reflecting what information you want to pass along. Something like:
```
print "<img src=http://www.site.com/my_image.gif?GRANDPARENT=".escape_
+uri($ENV{HTTP_REFERRER}).">";

```
So that the HTML generated ends up looking like: <img src=http://www.site.com/my_image.gif?GRANDPARENT=http%3a%2f%2fwww.domain.com%2fmy_other_page.pl">. Then, you can extract that information from the query string when serving the image (or from the access logs on that server, or whatever).

Thanks for the help guys, what I ended up doing is using javascript to get the referrer and the when then the program gets the referrer that was added to the query string in the image.	[reply]
