I added a "memory" source of my granduncle's headstone and tagged it as a burial source. The photograph of the headstone does not show up in the timeline as I hoped it would. Is there a way to get that to work?
Burial records - including memories attached/tagged as Burial - will show in Sources but in the Timeline these Vital Events use generic images - not attached memory photos. I don't think there is a way to change this currently. You can suggest this feature change in the Community Ideas:
Not sure if this is what you are asking, but each source has the menu option to ADD a date to each individual source. Then you have the option to arrange sources by date (ie, timeline).
