This may be a tall order, but is there any way to get photos in a google spreadsheet connected to an ArcGIS online map to show in the map pop up? I had a class of students survey shore access points in Seattle and I was hoping there was a way to make the photos visible while keeping them associated with their observation data. I have found that I could upload photos individually (not going to happen) or as a .zip (not ideal to have another layer, not sure if all the EXIF data is there). Any ideas?
