no grid view, but you should now be able to view larger photos in the page noted above by adding &options=bigger_image to the URL parameter list. (ex: https://jumear.github.io/stirfry/iNatAPIv1_observations_species_counts?place_id=7830&verifiable=true&spam=false&options=bigger_image)
since the desire for bigger images has been indicated elsewhere before, i’ve also added this option to https://jumear.github.io/stirfry/iNatAPIv1_taxa and https://jumear.github.io/stirfry/iNatAPIv1_identifications_species_counts.
