Figure 1，i have one or a few pictures，and some mp3 files. i want to develop a winform and load picture into winform，then, when mouse over certain areas of the picture，the area change，and play mp3 file when the mouse click.

question：How do I know the mouse over the designated area？and then change the color of the area？ how to know which areas of mouse clicks？ and play mp3 files

These areas may be round, oval, rectangular...
perhaps this is hotspot image question.
