For example, the following third-party pixel tag:
<img src="http://www.test.com/ads/?t=ap&px=123456&rnd=%n" width="1" height="1" border="0"/>
Would be edited as follows:
document.write("<img src='http://www.test.com/ads/?t=ap&px=123456&rnd=%n' width='1' height='1' border='0'/>");
<img height="1" width="1" src="http://www.test.com/action/This_is_a_Test"/>
document.write("<img height='1' width='1' src='http://www.test.com/action/action/This_is_a_Test'/>");
As shown in these examples, you must include
document.write, enclose the image tag within double quotes, and change all pre-existing double quotes in the tag to single quotes.
