In the storymap you submit items after choosing the right location, the right image and (if you want) a description.
On a previous occasion this week I recieved an error while transmitting. I tried a second time. After that the image and desription were twice available on the map. This time all went good, but the attached images are not displayed.
Is the storymap unstable ?
See ArcGIS StoryMaps
Go to the city of Eindhoven - the Netherlands and click for example on the two marked points.
