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/%22http://piwik.adminpanel.com/piwik.php?idsite=1&rec=1\%22
or
http://site.org/%22http:/piwik.adminpanel.com/piwik.php?idsite=1&rec=1%22
or
http://site.org/%5C%22http://piwik.adminpanel.com/piwik.php?idsite=1&rec=1\%22



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


in the pagesource it looks good:

<!-- Piwik Image Tracker -->
<img src=\"http://piwik.adminpanel.com/piwik.php?idsite=1&amp;rec=1\" style=\"border:0\" alt=\"\" />
<!-- End Piwik -->





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