Marker assignment via a custom field not working
The add-on allows you to use the images assigned to custom field options as markers. This is particularly useful if you've used a custom field for categorization. If the marker is not appearing on your maps you need to check a couple of things:
1. The field needs to be a single select or radio field because it's no possible to show more than one marker per listing.
2. The marker image needs to be placed in the add-on's icon folder. This means you will need to copy the image from the theme's theme_images folder to the icon folder where the add-on can find it.
