An intro element at the beginning of a project has visual appeal, and informs the user about the study. 

To add an intro element, go to the "More properties..." dialog for the group (e.g. Screener). Reference a new item "Intro" as the first item in the "children" attribute. 

The element will initially appear empty:

To add images and text, open the JSON editor and edit or add these attributes:

1. Set "type" to "empty" (line 4 below).The intro element doesn't contain data, setting type to empty will remove the 100% frequency bar for [NA]. 
2. Set "chartType" to "BasicElement" (line 16)-- this chart allows us to insert images and text in a "content" attribute.
3. Add a "content" attribute (line 17). Insert html code to add images and text. 
4. Add a "css" attribute to adjust the width of the images referenced in the content attribute. 

End result:

Expand the panel below to copy the JSON for the above element.
