maybe something like https://jumear.github.io/stirfry/iNat_observation_slideshow.html?user_id=becksnyc&taxon_id=47157. (just make sure to look at the usage notes on the base page https://jumear.github.io/stirfry/iNat_observation_slideshow.html. )

EDIT: there are also a couple more things described in this thread which might be relevant: https://forum.inaturalist.org/t/easy-way-to-export-into-a-field-guide/12632.
