Hi Tanya,You can override the OOTB pop-up, but I think it might get a bit complicated. Another option is to publish your services, create a web map in ArcGIS Online, and then open that web map in the Viewer. ArcGIS Online takes hyperlinks and provides a "More info" alias so you don't see the entire URL. Once you bring that web map from AGOL into Viewer, it maintains the "More info" alias even once you "Unlink" it. Give that a try, and let us know.Katy
