How to dynamically change an Image element source URL using a Parameter control element

When an image element is set to use an external link for its source, we are able to reference parameters within the URL. Using this feature, we can set a control whose parameters will be the URL to the desired images.

See below that the values for the List control element (whose control ID is “Market”) are image URLs for the Sigma and Snowflake logos respectively:


This way, changing the setting of the control will dynamically change the source for the image element to display because we reference the control element’s parameter value in its source Image URL using {{Market}}
