I am working on a research project with the University of Exeter as part of my master by research project on the Story maps and potentially useful hazard and risk communication tools. I have created a map in ArcMap that I want to use within a storymap, it is composed of TIFF image files with geo-referenced information which I got from Digimap, however I don't know how to get this map from ArcMap into a Storymap.
I have turned it into a map package and placed it in my online account but I can't get it then to load into ArcGIS online where I can save it as a webmap for use in my storymap.
Any help would be greatly appreciated as I am starting to pull my hair out a bit,
