Hi, I tried to follow this exact tutorial: Interactive Images in StoryMaps (arcgis.com)
When I come to the step of sharing my selected layer as a web layer, I can't click on Publish or analyze if I choose Tile as layer type. If I choose Feature layer type and analyse before I share, I get this:
Solved! Go to Solution.
To circle back, looks like this was due to not having publishing permissions?
Did you try to save the georeferenced image as a new image so that the sharing recognizes the spatial reference?
That error message looks like you are sharing an image file as a feature later not a tile layer, check the sharing configurations for tile layer settings and options.
