Image with Hotspots

Can you replace the background image on existing content with hotspots? I have created an image with at least twenty hotspots (with title, metadata and corresponding text/description). I would like to be able to keep all the hotspot information that I added, but replace the actual image with an updated one. (I know I would have to replace the location of the hotspots on the new image.) Is this possible? The only way I can see to do it is to delete what I have and start again with the new image.
