One affiliate network I promote will add a tracking pixel for you but won't add any javascript. I've sent them my adwords, msn, and yahoo conversion code and they've added the URL to a pixel.

Google and MSN track fine but Yahoo doesn't. We've tried to decipher the URL that yahoo creates with the JS but it's not working.

Here's what we've got:

<img src="http://srv1.wa.marketingsolutions.yahoo.com/script/ScriptServlet?aid=#*$!#*$!#*$!#*$!#*$!#*$!" width="1" height="1" border="0" />

Yahoo support says their JS is in fact making a tracking pixel but they didn't know how to get the actual URL that it creates. I've looked at an actual landing page with the yahoo code but I don't see that it's making a pixel.

Does anyone know how to get this to work with yahoo? Any other suggestions on how to accomplish this?

Thanks a bunch.
