Question regarding embeding dimension values to image file
I have a question regarding adding dimension values to image file.
Suppose i have a image which is a subway station map (not a map) and i have a dimension column which is list of all the subway station. I would like to embed my list of subway station name to this image so that whenever i move over my mouse pointer to particular station, it will show various kinds of stats of that particular subway station.
I know this could be implemented when i use maps( such as google map) and corresponding coordinate data set. However, I would like to know if there is anyway to embed dimension values to image so that i could display corresponding data wherever i locate mouse pointer to specific location of that image.
