Broken Tracking Image

Was read FAQ carefully, and made some test

After clicking on Broken Image in FireFox and click Open Image I see that path for Image is looks like this:

http://site.com/"http://piwik.adminpanel.com/piwik.php?idsite=1&rec=1"
or
http://site.org/"http:/piwik.adminpanel.com/piwik.php?idsite=1&rec=1"
or
http://site.org/\"http://piwik.adminpanel.com/piwik.php?idsite=1&rec=1"

I think it should be just like: http://piwik.adminpanel.com/piwik.php?idsite=1&rec=1

in the pagesource it looks good:

<img src=“http://piwik.adminpanel.com/piwik.php?idsite=1&rec=1” style=“border:0” alt="" />

So how can I resolve my problem?
Thanks in advance to everyone who can help! =)
