Since FileMaker Pro has integrated Web Viewers and with the addition of FileMaker’s fmp:// url, we’ve long been able to integrate images with irregularly shaped areas offering any number of polygonal objects which are user clickable. If you deal with any kind of map, seating chart, irregular shaped real-world object which requires specific defined areas, then look no further than HTML Image Maps. No Flash required here.
