When I extract an "Image tag" for a zone (with generic 3rd click tracking) this is what my ad tag looks like -
<a href='http://<adserver>/delivery/ck.php?n=abcd123&cb=INSERT_RANDOM_NUMBER_HERE' target='_blank'>
<img src='http://<adserver>/delivery/avw.php?zoneid=100&cb=INSERT_RANDOM_NUMBER_HERE&n=abcd123&ct0=INSERT_CLICKURL_HERE' border='0' alt='' /></a>
INSERT_CLICKURL_HERE is replaced with the 3rd party click tracking server.
But the clicks are not reaching the 3rd party server. The click does go to the final destination url and gets tracked in revive ad server however it never goes to the 3rd party server.
The same tag if extracted in the JS tag format, works and clicks are tracked in 3rd party server. The issue seems to be Image tag only. Not sure what am I missing here.
