Productivity: stretch shrink multiple slides pictures at once

[MusicalBox]

Hi @izzylaif
See this discussion:

Easy way to make video slide show ends with audio track?

I have a couple of dozen of still images that I want to spread over the duration of an audio track to create a slide show with music. How do I spread them out evenly and ends at the same time with the audio track. Complete with transition between all the still images?
