I can’t answer for the original poster, but what I would love to have is a slideshow that works as a picture gallery. It would show the first photo from each observation (or from each taxon) and cycle through those images (perhaps in random order) with the taxon name and observer shown for each. Each image would show for maybe five seconds. This would be a really cool thing to have running in fullscreen mode at the welcome area for a BioBlitz, especially if it updated so that people could see the images they’d added appearing.
