How do I use a georeferenced .jpeg as a basemap?

[AdamAllen]

I have some custom aerial imagery that I've processed into a georeferenced .jpeg. I'd like to use that .jpeg as a basemap for an ArcGIS Online web app. What's the best way to go about this (thinking I'll have to start by converting my .jpeg to a georeferenced .tiff - which I have done)? Any help/resources would be appreciated. Thanks!

You could Publish hosted tile layers from files—ArcGIS Online Help | ArcGIS and add the service as basemap (Choose basemap—ArcGIS Online Help | ArcGIS )
