Hi Julie,
My above answer to Nakib's question applies to your question as well. You have two choices:
- Use an Eloqua dynamic element in your landing page and then define the rules for the dynamic element based on the value of a field on your Contact table or a Custom Data Object
- with this option you would be limited to adjusting the image on a per user basis - not based on URL variable.
- users would already need to be in your databaseUsers would have to be known by Eloqua (non-anonymous) in order to use this, otherwise the default image would be shown.
- Use Javascript to grab the query string and change the image on the fly.
