I am working on a story map and for my layer I would like to have a picture for every single location to be shown on the pop-up. I have followed everything on this link: http://doc.arcgis.com/en/arcgis-online/create-maps/configure-pop-ups.htm , but other than getting a picture icon in my pop-up, the picture doesn't show up.
I wonder if it is something I should change in my attribute table, like using an actual picture in my computer, or a picture on the web? or some data formatting I need to do in order to make this happen.
