If you want to delete an event from your iPhoto library, there are a few different ways to go about it. The first way is to use the “Edit” menu in iPhoto and select “Delete Event.” This will open up a dialog box where you can choose which events you want to delete. If you want to delete all of the events from your library, you can use the “Clean Up” feature in iPhoto. This will scan through your library and delete any events that are no longer needed. ..
