I would like to generate a Story Map Swipe representing changes in the time. However, when I imported raster files which are stored as *.sd files in my server I am not able to save the generated story map. I think that the problem might be with the size of my sd file (4 sd files which have: 1.8GB, 1.7GB, 1.1GB, and 1.0GB, the *.sd files store raster TIFF files which have 11GB, 11GB, 1GB, and 1GB). I imported these raster as Web Map - all rasters are stored in one Web Map. Is this might be the reason why I cannot save my story map, or is it something else? Thank you in advance for help.
