I have a blank feature layer that is going to be used with a AppStudio app for data collection in the field. Before the app is deployed we have around 75 pictures that were collected in the field using individual's cell phones.
I am looking for a way to add these photos to the feature layer in ArcGIS Online but have been unable to find any way to efficiently do this. Should I do it in ArcMap and then replace the feature layer with that was created using ArcGIS Online?
I am just looking to see if there is a simple way to do this or will I have to go one-by-one?
