Switch image when switch light/dark mode

[mcatze]

I use a user field with an image in the message template. When I use the light mode the image is visible, if I switch to dark the image isn't visible. Is there a trigger and/or can I use a if/else statement in the custom user field entry in the app?

Code:

if light mode > image001
if dark mode > image002
