Adding 3rd Party Tags

For some banners a 3rd party tracking pixel needs to be added into the HTML-container in ASX. This can cause issues in Firefox (a blank line displayed above the banner), to avoid this insert the following style in the IMG-tag:style="position:absolute;bottom:0px;right:0px;z-index:100;". See example below.

Original tracking pixel:

<img src="http://some.tracker.somewhere.com/?q=0123&z=456" width="1" height="1" border="0">

After adding the style:

<img src="http://some.tracker.somewhere.com/?q=0123&z=456" width="1" height="1" border="0" style="position:absolute;bottom:0px;right:0px;z-index:100;" />

Secure sites (HTTPS) and 3rd Party Tags

If possible, always make sure that your third party tag is https compatible. If not, your ad will not run properly on secure sites. Either use tags with resources explicitly pointed as https://, or use the {protocol} macro to have the protocol be subsituted in real time.

If you are unsure about https compatibility of a third party resources that is given with an explicit http:// protocol, try substituting http with https, and open the URL in a browser. If it loads properly, your tag is likely https compatible. 

Always consult the vendor of your 3rd party tag if possible for information about https.
