power point or google slides

Hi. I am not a business, i'm a fixed income senior who likely could figure out how to use either power point or google slides. I am likely showing my age - perhaps these have not been in use for a decade! I have some audio, and some pictures. I'd like them combined in a 4 to 6 minute slide show. Can you help? Its a volunteer situation but i do have fresh eggs, dahlias, and pears to thank you.
