I have an image which I want to make it zoomable and dragable in browser, and draw some overlays like lines and markers on it.
So I wonder if I can use the map api like Google map or openlayers to load the image. Then I can use the draw feature provided by the API to add overlays.
Since the image size is not fixed ,some of them are almost 100M. So I may have to generate tiles first, but the image have no coordinates, so I do not know if it is possible.
