There are four types of pixels. They are as follows:
An image pixel is a tracking URL located on the confirmation page inside an HTML image tag. The following example shows an image pixel:
<img src="http://www.domain.com/pixel.track" height="1" width="1">
A ServerSide pixel is a pixel URL executed by the back end instead of from the confirmation page. A ServerSide pixel is just a URL that should be executed with each conversion. The following example shows a ServerSide pixel:
<iFrame scr="http://www.domain.com/pixel.track" ></iFrame>

This feature works when you have a LinkTrust Java Script confirmation pixel placed on the confirmation page. This code placed in the open text box is pulled down to the confirmation page for all successful transaction. If you have additional code for a specific affiliate, it is recommended you place that code in the pixel section of the affiliate’s details. The additional code added will only be pulled to the confirmation page when the affiliate is responsible for the successful transaction.
You can also allow affiliates to manage their own code from the affiliate center.
