creating a legend in Finder app

[Anonymous User]

I have started creating some Finder application maps (Parcel, Planning Filings) and my co-workers have enjoyed being able to search data on a larger scale than just addresses. What I was curious about is the ability to add a legend to the map. I'm not seeing anyway to configure one or any code on GitHub to add one. It would be nice to show what the various symbols mean. Any help would be greatly appreciated.

Gotcha.  You do that in the application configuration.  Here's a picture of the configuration editor (the right-hand panel)...It's in the same spot where you write your help text.

Just add text like:  <img src="pic_mountain.jpg" alt="Mountain View" style="width:304px;height:228px">

I am hosting this template so the configuration app is not available. I'm having a difficult time trying to figure where/what file to modify for adding the image to the help popup.

So, you'll want to edit the Finder.json - in my file it is line 35.

You edit the tag for helpMessageBox.content.

Here's an example:

"helpMessageBox.content": "<b>Picture of a Duck</b><hr>\n<br>\nHere is my awesome picture of a duck.\n<br><br>\n<b><img src=\"http://www.hdwallpapersinn.com/wp-content/uploads/2014/08/Swim-Baby-Duck-Wallpaper-Cute-Animal.jpg\"...>"
