The only way it could be done with precision is to manually create a slideshow by placing your images on the timeline yourself and adjusting the duration to match the beat of the music. But you can't apply one of the templates I am afraid. You could add the "Magic Motion" tools to add some visual interest. You could also predetermine and calculate a duration for each image you place on the timeline in advance. So for example, your music is 128 BPM. You want the slides to change every 8 beats. So that would be a duration of 3.75 seconds. You can then go into your preferences and change the default duration of your image in the editing menu and change the duration to that time. Then when you drag all your images to the timeline they will ALL have that setting . Then add your music and experiment with changing the duration to get it to your liking.
But the Slideshow templates that are in Power Director are what they are. Some of them allow you to adjust image placement within the show, but the duration of each image is not adjustable, they are predetermined in the template.
