I’ve created a one-hour slideshow,on photostory deluxe 2025, but I’d like to delete an image without affecting the synchronisation of the titles and music with the rest of the slideshow.

W11 on 11th Gen Intel(R) Core(TM) i7-11700 @ 2.50GHz (2.50 GHz) RAM 32 NVIDIA GeForce GTX 1050 (3 Go)

thank you for your advices
