tracking pixels

[EliteRides]

Just curious in how you guys ( and girls ) incorporate tracking pixels into your sites. I took over managing a site for a company and the current tracking pixels on their site for their clients are just loaded each time for every tracking pixel. In other words, every affiliates' tracking pixel is loaded every time the final page is loaded... even if their business didn't refer the sale.

Just curious how others have theirs structured to load only from their respective referring url.

Is there a way to load an image (pixel) only if the url contains leadid=referrer1... then it would load referrer1.gif? Maybe with some sort of php.

<img src="{leadid}">

And then the page would contain:

referrer1=http://www.referral1.com/pixel.gif
referrer2=http://www.referral2.com/pixel.gif
referrer3=http://www.referral3.com/pixel.gif

Nevermind. I found a way to accomplish this with PHP. Thanks.
