5.11 Fields for Images ↑
5.11.2 Image Name Dark
This is a field that can be used to specify an alternate image for use when the app appearance is set to dark.
Note that the field type is still imagename, but the field label contains the word dark.
See the following for an example of what this might look like in the Collection’s template file.
Image Name: <imagename>
Image Name Dark: <imagename>
If you like, you can set both the image name fields to display the same image. However, if you don’t set the dark image name and you are using a Dark display, then no image will appear.
